What should I do with freckles on my face?

What should I do with freckles on my face? 1. Depigmentation and exfoliating treatment for hydroquinone cream, tretinoin ointment, arbutin cream, azelaic acid cream, fruit acid, trichloroacetic acid, etc. Some freckle removal products are intended to inhibit melanin synthesis or accelerate melanin metabolism and have a certain effect. Some freckle removal products are mainly for exfoliating keratin. Most people cannot correctly distinguish the principle of action of various freckle removal products. There is no way to master the concentration and use method. If improper operation and care are used for a long time, the skin will become thin and sensitive. Many medicines remove freckles, traditional Chinese medicine remove freckles, and the damage of skin barrier function brought by chemical peel treatment is very, very, very difficult to recover. Clinically, customers who encounter sensitive muscles every day, part of them are those who have used various kinds of freckles, or have done strong exfoliative treatment and improper care. 2. Destructive treatment has used liquid nitrogen freezing, high-frequency electricity, CO2 laser and other treatments in the past, all of which can make freckles exfoliate, but the above treatments are not selective for skin lesions, and often cause some sequelae. May cause scarring and may cause pigmentation or decrease. Now this kind of treatment is relatively rare, and the doctor’s operation skills are very high. 3. For current medical treatment, strong pulsed light and Q-switched laser are undoubtedly the first choice for freckles. The principle of treatment is “selective photopyrolysis”. The energy of the laser or photon is selectively absorbed by the pigment bodies in the freckles, and the blast effect is instantaneously broken. The crushed melanin dust may fall off with dandruff or be swallowed by macrophages and then excreted with the lymphatic circulation. Since the energy is selectively absorbed by the pigment, the surrounding normal skin will not be damaged, so the freckle removal effect is very safe. As long as the treatment process takes more than 10 minutes, it will not affect the general life and work after the operation.

Is it true that wearing a white mask will reflect ultraviolet rays and cause black moles or freckles?

In the scorching sun, many people have various skin problems because they wear masks for a long time. Korean media reminded that many masks cannot cut off the ultraviolet rays, and it is necessary to take good sun protection measures when wearing them, especially if the white masks are not worn tightly, it will reflect the light, causing black moles or freckles around the eyes and nose, so it needs extra note. &nbsp. Since the appearance of this report, many fans have left a message asking me: “Is it true that wearing white masks will cause spots? Is my new spot because of wearing white masks?” There is only one truth: indeed, many Color spots are related to ultraviolet rays in sunlight, and white objects or mirror objects reflect light more strongly, which will aggravate the damage of ultraviolet rays to the skin. But even in the daily environment (especially in the snow, seaside, glass curtain wall, road, etc.), there will be light reflection, so in addition to the protection of parasols and hats, we also need the protection of sunscreen every day. However, the cause of color spots is very complicated, not only because of ultraviolet rays, it is not necessary to reject white masks, and it is enough to do sun protection. So what should we do with the spots that have formed? Today I’m here to help you figure out what is happening to your spot and how to deal with it effectively. Some “spots” have been from a young age-freckles and freckles must be familiar to everyone. After all, there are many elements of freckles in various pictorials. Good-looking freckles make people feel more girly and have a retro feeling. , I really like it. But freckle makeup is one thing, freckles is another matter, after all, no one can guarantee the number of freckles appear, long position as you wish. A small number is acceptable. I’m afraid that my eyes will be spotted, so I don’t want to look good at the director, which happens to be the case in most cases. Freckles are mostly small, brown dots, which are generally symmetrically distributed on the cheeks, or grow on the nose, the genetic factors of freckles are very large. Sun exposure is also a cause of it. Some melanocytes malfunction due to the production function, and blindly produce melanin, some parts of the face will surrender to become black. The little cute with freckles will find that the vibrant freckles in summer will settle down in winter, and the color is no longer so dark. The clever little cute should have grasped the point, if you want freckles not to become a wild horse, please do a good job of sun protection~&nbsp.Some “spots” are destined to be brown and blue moles, although brown and blue moles are often in adolescence It will appear later, but its onset is believed to be determined during our embryonic development. It is because of the hidden danger that melanocytes migrated from the neural crest to the epidermis at that time, failed to pass smoothly, and were trapped in the dermis. In most cases, the face is symmetrically distributed on both sides, and the grayish brown and cyan round or oval spots are easily misunderstood as “black circles” if they are right under the eyes. Some “spots” are related to age-seborrheic keratotic plaques are also called “senile plaques”. Although this alias is very impolite, seborrheic keratotic plaques do have something to do with age , Often appear on the face of friends over 40 years old. It is related to the cumulative effect of ultraviolet rays, frictional irritation of the skin, and other factors. It is often expressed as a dark brown spot with clear boundaries, and sometimes the surface will thicken. Some “spots” are irritated-pigmentation after inflammation When our skin is acutely injured (trauma, insect bites, etc.) or chronic irritation (eczema, repeated friction to stimulate the skin, etc.), the inflammatory reaction reduces the skin’s thiol groups. The activity of the enzyme is released and local melanin synthesis is increased. Due to the inflammatory reaction often accompanied by the expansion of capillaries, the initial pigmentation after inflammation often appears as brown spots with redness. But unlike other stains, pigmentation can improve on its own. When the “inflammation” of the fuse disappears, the pigment will slowly subside, but some will take weeks and months, and some will last longer. If you can’t retreat for a long time, you can also choose tranexamic acid orally according to the specific performance, or fruit acid rejuvenation to help pigment metabolism. Some “spots” make doctors have headaches-chloasma chloasma can be regarded as the most headache stains for doctors. Its annoying one is that it is difficult to treat and has a long cycle; the other is that it is easy to repeat and is impermanent. Such erratic and erratic spots not only affect the mentality of friends with melasma, but also test the doctor’s professionalism and patience. The cause of melasma is complex and may be related to hormone levels, improper use of drugs or skin care products, skin barrier function, genetics, ultraviolet rays, some chronic diseases, emotional and psychological factors, etc. Multi-symmetrical distribution on the face, light and dark brown

Does laser freckle need sunscreen?

&nbsp. “Banhua” is held by everyone, but “Banhua” can only be treaded by everyone. Therefore, we should do “class flower” instead of “spot flower”. Laser freckle removal will undoubtedly allow you to easily get rid of the “spotted flower” and become a “class flower”. So does laser freckle need sunscreen? I believe it is also a problem that everyone is more concerned about. Below is a Hangzhou time medical aesthetic expert for you.  Experts said that for a more comprehensive understanding, does laser freckle need sunscreen? It is important to understand laser freckle removal first.   Laser freckle removal: The laser emitted by the treatment instrument can penetrate the damaged skin very smoothly, enter the damaged part, and treat the pigment of the damaged part. Spot pigment will change under the powerful laser irradiation, and then dissipate on its own, thus being cured. The laser does not forcibly remove the pigment, but it is treated through the skin, but it will leave scars after the treatment, and because it is selective, that is, it only acts on the pigment particles and does not damage normal skin.  The advantage is mainly reflected in: laser freckle removal is more accurate on the eyelid and yellowish freckles, and still has obvious effect. The laser can selectively heat, rupture, solidify and wither the pigments in the spots, that is, to destroy the freckle tissue as much as possible, but there is no obvious damage to the normal skin around the freckles, and freckles will not leave the skin unsightly. scar. So as to achieve the ideal treatment effect, no obvious side effects after surgery, generally only need to be treated 1-2 times. After using laser freckle removal, not only can freckle removal, but also laser skin rejuvenation characteristics, improve skin texture, whiten skin, eliminate fine wrinkles. Laser freckle care: After the laser freckle is removed, the skin is irradiated by the laser, and some people will have redness and swelling of the skin. This is a normal phenomenon, and sometimes a slight bleeding occurs. This is a normal phenomenon and will fade quickly. Don’t worry . Generally, the wound will be removed in about a week after the scab is formed. After the scab is removed, the skin is soft and pink. At this time, the skin must be clean and hygienic, and prevent sun exposure. Don’t go out, if you go out, you need to do sun protection. If the pigments have not all faded in about three months, then after expert diagnosis, laser freckle removal can be performed again. It is strictly forbidden to eat spicy, non-smoking wine and other irritating food.

Do you know how laser removes chloasma?

&nbsp.   Many girls in their early twenties have chloasma problem. Chloasma is a skin disease that many young women often have. This disease seriously affects women’s image, so for chloasma patients, early acceptance Treatment is very critical. There are many ways to remove chloasma. Laser treatment is one of them. So how does laser effectively remove chloasma? The doctor at Hangzhou Time Plastic Surgery Hospital is popular for everyone.  Many people are not very familiar with this. Let’s introduce this issue in detail.  Principle of laser to remove chloasma: laser instrument produces a high-intensity beam, different types of laser can produce different colors of light. The naked eye color of the laser is the key to treatment. Lasers of different colors are absorbed by the skin of different colors, and the laser energy is used to disintegrate and vaporize the dye particles, close the blood vessels, and then absorb the dye particles by the body to remove the chloasma, and the pigment fades.  The effect of laser to remove chloasma: This method of laser to remove chloasma can produce high-energy, focused and accurate monochromatic light, with a certain penetration, and can produce high heat locally when acting on human tissues. Laser can be called an effective method for removing chloasma. Laser freckle removal can quickly and effectively remove the patient’s chloasma, and there will be no treatment problems. The laser uses a variety of advanced laser instruments, which can effectively penetrate the skin surface layer, cause the pigment particles to swell, rupture, and form tiny fragments in an instant. The body is swallowed to remove the body, so that the chloasma can be removed effectively. . Laser light removes chloasma. This light wave can absorb black and brown pigments, and the spots can be absorbed by this type of laser and be decomposed. When the pigment is gradually absorbed by the body, the color will also change. Tattoos and tattoos belong to this type of pigment .  Remove melasma with laser should pay attention to postoperative care: usual lifestyle will determine whether your melasma removal is successful, so pay attention to the combination of internal and external. The laser can selectively heat, rupture, solidify and wither the pigments in the chloasma, and destroy the chloasma tissue as much as possible, but there is no obvious damage to the normal skin around the chloasma, and the effect is better. But the general treatment at this time is related to the patient’s physique and the size of the plaque.  After the laser removes the chloasma, the skin will be red and swollen. The beggars need not worry. This is normal and the redness will disappear quickly. In order to restore the skin to health earlier, it is recommended that beauties apply some anti-inflammatory cream every day. In addition, experts also pointed out that during the treatment process, it is necessary to pay attention to maintaining hygiene and avoiding the exposure of strong light, so as not to have more serious effects on the skin.

Whitening a summer|Repair after sunburn This is no longer afraid of sunburn!

In summer, what is the most important point about skin care? Sunscreen is definitely in the top three! But some babies are curious: why I obviously have enough sunscreen “three-piece suit” (sunscreen, sun umbrella, sun protection clothing), but after a summer, geese still have unavoidable rough skin, uneven skin tone, not easy to put on makeup, dark Shen’s “Fate”? Many babies think that sun protection can “not tan”, but in fact, UV damage to the skin is far greater than we thought. Even if the hin of daily sun protection is in place, the little goblin of ultraviolet rays will still be invincible. The tanning that babies usually worry about is because of the long-term exposure to ultraviolet rays, our skin will be self-preventive. The melanin in the skin will increase. Over time, the melanin will be deposited in the skin epidermis, and the skin color will start to darken. Will subside easily. In addition to the precipitation of melanin, the moisture of the skin after exposure will be significantly reduced, and the loss of collagen will make the skin more dry and wrinkled, destroy the elastic fibers, and appear aging. Over time, these problems will slowly “find the door.” Babies with poor skin resistance will become more sensitive after the “damage” of ultraviolet rays, causing skin damage and tingling and itching. In severe cases, there may even be peeling, folliculitis, and skin diseases. Therefore, post-sun repair is as important as sun protection. Doing this step well can greatly reduce the damage of ultraviolet rays to our skin. Not only avoid tanning, but also prevent various skin sequelae! Repair after sun exposure should not be blind. These two misunderstandings should avoid washing your face with hot water. The skin after sun exposure is sensitive and fragile. If you wash your face with hot water, the capillaries will be dilated and congested, causing erythema and sunburn. Therefore, you must wash your face until the skin is at room temperature, and clean the face with warm water to calm and reduce redness and heat. Don’t rush to whiten after sun exposure. After the sun baptism, in fact, the skin needs to be soothed and calm. At this time, you can use lotion or pure water cold and wet compress or choose some moisturizing cream, which can relieve the skin sun. The post-stress response can calm, soothe and soothe the skin, allowing the skin to recover from the burning sensation after sun exposure to a calm state. Remedy: supplement dimension C and dimension E. Since post-sun repairs should not be underestimated, how should post-sun repairs be performed? Get these several after-sun repair whitening solutions and shake hands with the sun! Fruit acid peels can be operated immediately after sun exposure, once a month, 2-3 times; inhibit melanin and reduce pigmentation. The molecular weight of fruit acid is very small, it can effectively penetrate into the pores of the skin, separate and soften the cuticle cells of the epidermis to make it naturally fall off, promote the skin cells to accelerate the renewal, increase the skin elasticity and gloss, fruit acid beauty shrinks the large pores, strengthens the whitening ingredients Penetration. Half a month after photorejuvenation, you can start photoelectric projects, such as photorejuvenation. Once a month, 3 times in a row; photorejuvenation is mainly caused by strong pulsed light acting on skin tissue to produce photothermal and photochemical effects. On the one hand, it can rearrange collagen fibers and elastic fibers in the deep part and restore elasticity, and at the same time make blood vessels Increased tissue function and improved circulation, eliminating or reducing facial skin wrinkles and shrinking pores. On the other hand, strong pulsed light can penetrate the skin and be preferentially absorbed by pigment groups and blood vessels in the tissue, without destroying normal skin. Under the premise, the blood is coagulated, and the pigment clusters and pigment cells are destroyed and decomposed, thereby achieving the effect of treating capillary dilation and pigment spots. Whitening water needle can stimulate skin metabolism, accelerate skin metabolism while hydrating, improve skin texture, improve dark yellow dry skin, brighten complexion, brighten skin, brighten skin, and improve face and eyes The role of small wrinkles around the week. Adding appropriate glutathione or tranexamic acid to the water light needle can nourish the secretion of pigments, improve the dull skin color, lighten the effect of spots, and have a certain whitening effect on the back of multiple injections. Can be used in conjunction with various sunscreen products. Apply sunscreen daily, regularly use after sunburn to do post-sun repair, brighten for longer!

Vitiligo treatment, it is important to distinguish the types!

In order to facilitate the research and treatment of vitiligo clinically, it is divided into three types, two types and two phases according to the scope and distribution of vitiligo. (1) Divided into three types: 1. Limited type: skin lesions are limited to a certain part. ① If it only affects one part of the lips, perianal or external genital area, it is called mucosal type. ②The innervation area of ​​one cutaneous ganglion involving one side is called segment type. 2. Pan hairstyle: This type is the most common. ①Common type: The lesions are generalized and distributed roughly symmetrically. ② Facial and extremity types: The lesions are distributed on the face and distal limbs, such as the back of the hands, fingers, and insteps. ③ Mixed type: a combination of several different types mentioned above. 3. Whole body type: The skin of the whole body is completely or most of them affected and turned white, and even hair can be turned white. (2) Divided into two categories: 1. Completeness: The white spots appear pure white and porcelain white. There is no pigment regeneration in the white spots, the melanocytes in them disappear completely, and the Dopa reaction is negative. 2. Incompleteness: Pigment spots can be seen in the middle of the leukoplakia, the melanocytes in the leukoplakia are reduced, and the dopa reaction is positive. (3) Two stages: 1. Progress stage: the number of leukoplakia increases, the range increases, the boundary is blurred, and a homogenous reaction may occur. 2. Stable period: The leukoplakia stops developing, the boundary is very clear, and the normal skin pigment at the edge is deepened.

How to eliminate postpartum stretch marks?

Being a woman is not easy, you need to experience the pain of having a baby, and then you have to endure the torture of stretch marks. If you do not fight, you will be overwhelmed by childbirth. In the face of stretch marks, if you let it go, it may damage your appearance and affect the happiness of the couple. Many people will ask, how to eliminate postpartum stretch marks? The following is a popular science for you by the doctor of Hangzhou Time Beauty Hospital. How to eliminate postpartum stretch marks? Stretch marks will not be eliminated by themselves, because these marks are caused by the growing muscles of the baby during the growth process, causing the muscle fibers around the mother’s stomach to crack, and the muscle fibers belong to the category of dermal tissue. If it cannot be effectively compensated by its own self-healing ability, it must be treated by corresponding methods. For postpartum stretch marks, you can use the laser method to eliminate it, which is an effective method of skin beautification, and has a very good effect on various skin problems left by pregnancy. The laser can directly stimulate the damaged collagen layer to produce new collagen tissue. These new collagen tissues will grow at a normal rate and gradually repair the damaged collagen layer, thereby effectively replacing the broken muscle fibers, so that the stretch marks will be It slowly disappears, and it can also improve skin texture and increase skin resistance. Laser skin beautification can not only remove stretch marks, but also fundamentally improve various pigment spots, especially the deposition of pigment spots caused by endocrine changes during pregnancy. It can directly reach the pigment of the dermis, crush it through the instantaneous high-energy effect, and then slowly excreted through the body’s metabolism to achieve a good freckle removal effect.

Do you know all the information about “moles”?

Pigmented moles are composed of pigmented mole cells. According to the distribution of mole cells on the skin, they are divided into three types: border moles, intradermal moles, and mixed moles. Moles may already exist at birth or gradually appear in the early years after birth. It can be said that there are “moles” that are not young. So, do you know the following information about “moles”? How is a mole formed? Pigmented moles are because melanocytes are transported along the nerve muscles during individual development. During the transportation process, melanocytes are stored due to external factors (including genetic factors), and melanocyte moles are formed on the surface of the skin. It is related to the development of the individual. Pigmented moles are almost everyone, only the number or size is different, it can occur in any part of the body, most pigmented moles do not need to be treated. According to the difference in histology, pigmented moles are divided into three categories: * Junctional moles: growing at the junction of epidermis and dermis, most of them are born, and will grow into dermis into intradermal moles with the age, growing in the palm , Exposed parts of the plantar and external genitalia. Due to long-term friction, trauma and infection, it is more prone to malignant transformation. *Intradermal nevus: Pigmented tissue is located in the dermis. The clinical manifestations are pigments of different shades, mostly round, higher than the skin surface, and can grow body hair. It is a common pigmented mole and malignant transformation is rare. *Mixed moles: It has the characteristics of junctional moles and intradermal moles. The appearance is similar to intradermal moles. The pigment distribution is not as regular as intradermal moles. The central pigment is deeper and diffuses around. Malignant changes are relatively rare. Most of the border moles appear in infants or children. With the increase of age, the junctional moles gradually evolve into mixed moles, and the proportion of junctional moles gradually decreases. After puberty, most junctional moles, mixed moles, become intradermal moles. 2 Moles, what do you need to pay attention to in life? “Avoid stimulation”! The most important thing we need to pay attention to is to avoid friction and irritation as much as possible. Pigmented moles are common to everyone, and normal individuals can be up to 50, with an average of 15-20. Do not use medicine to irritate moles. If the treatment is not good, it will leave unsightly scars at the worst and induce moles at the worst! I have seen people clinically remove or remove moles on their own. When they came to the clinic, they saw that the integrity of the rash was significantly damaged. At this time, the possibility of malignant transformation may be significantly higher than that of the original mole. 3. Which moles should be removed prophylactically? ①pigmented moles on palm and plantar and other rubbed parts; ②pigmented moles on nails; ③ moles that relapse after treatment with electrocautery, chemical corrosion, freezing, laser, etc.; ④ pigmented moles with larger diameters that were born. 4 How to treat pigmented moles sensibly? Some people have listened to the nonsense of the messengers who want to remove the moles in order to “exorcise and bless”. Some people are too worried, but they are afraid of evil changes, and they will not be panic all day long. They talk about “moles” color change. These practices are undesirable. It is the only feasible way to understand the medical principles and accept the doctor’s regular treatment. Common pigmented moles do not generally need treatment. The general principle is that if they are not cured, they will be completely cured. Pigmented moles, which are usually located in special parts of the nasal cavity, oral mucosa, palms, soles, vulva, anus, genitals, etc., are prone to malignant changes due to frequent friction. It is recommended to remove them as soon as possible. If necessary, dermoscopy can be used for testing. Optional treatment strategies include ionized laser, chemical corrosion, surgical resection, etc. The choice of specific treatment depends on the location of the mole. For example, if you have a face, you can choose plastic surgery to ensure the appearance; the lumbosacral region is less casual. The principle of mole removal: complete removal: moles with a diameter of less than 2mm can be treated with laser, but there are still risks: easy to relapse and malignant transformation, and surgical removal can remove the mole cells cleanly. 5What should I pay attention to after the operation? ① The wounds should be kept as dry as possible within one week after spotting the mole. After washing or touching the water, gently blot them with a clean towel as soon as possible. ② Avoid pigmentation caused by sunburn, pay attention to sun protection and protect skin. ③ Eat less spicy and spicy food and eat more foods containing vitamin C. ④Do not scratch at will to avoid infection affecting wound healing.

What are the ways to freckle

When it comes to the method of freckle removal, the second best is laser freckle removal. Its fast and good effect is also welcomed and loved by everyone. Simply put, the principle of laser freckle removal is to irradiate the color spots to decompose the pigment and eventually excrete it with the metabolism of the human body. The laser beam only acts on the pigment particles and does not damage the epidermis, just like the flashlight is irradiated through the glass at night, and the glass has no damage. Furthermore, the area of ​​the laser beam is small, and it passes through the skin in a very short time of milliseconds, nanoseconds, or even picoseconds. The thermal damage to the epidermis is minimal, and no scars will be left after freckles. Frequently used freckle removal instruments: M22, super picoseconds.

The 5 most common mistakes in medical beauty are laser freckle

I have seen many beauty seekers who are deeply troubled by long spots, no matter what age they are unavoidable, but this is not the worst. The worst is that small “spots” become large “spots” and shallow “spots” “Darken” “spots”, “spots” are more than just one spot is not terrible, the scary ones are those that are invisible to the naked eye. Laser freckle removal is currently the most effective and advanced method of treating stains, but many people also have some “prejudice” about this, fearing that the treatment will not be clean, fear of rebound, fear of side effects and so on. 5 mistakes of laser freckle, have you successfully avoided it? Will laser freckle leave scars? Because the laser of a specific wavelength can reach the pigmented tissue of the lesion through the epidermis and dermis, it only acts on the pigment particles. The epidermis of the skin is basically not damaged, so it will not leave scars on the skin. Lasers of different wavelengths can be selectively absorbed by the pigments in the skin. Furthermore, the laser beam has a small area and passes through the skin in a very short time of milliseconds and microseconds. The laser’s heat loss to the epidermis is very small and will not Scar the epidermis. Laser freckle removal only needs one treatment. Laser freckle removal is not a single treatment. Generally, laser freckle removal requires about 1 to 5 treatments, and the interval between each treatment is about 1-2 months. The frequency of laser freckles is mainly related to these two factors: ① The beauty of the person who seeks the beauty, the skin type and the type of color spots are different, the number of laser treatments is also different, and the area of ​​large spots and dark colors is more. ②The choice of laser equipment, there are many laser equipment used for freckle removal, and the treatment times of different laser equipment will also be different. Laser freckle can completely treat chloasma. After multiple treatments, laser does have a very good therapeutic effect on certain spots such as freckles and age spots, but freckles are a disease that is closely related to heredity. In general, there is a possibility of relapse; and after treatment of senile plaques, some beauty seekers may relapse. As for chloasma, laser is currently the most commonly used method for the treatment of chloasma. Although there is no guarantee for cure, most people seeking beauty are still effective. Laser freckle treatment will bounce back after so-called “bounce”. Generally speaking, it refers to the phenomenon that the treatment effect is repeated, the effect is significantly reduced, or the stain becomes darker after treatment due to the instability of the treatment in a short time. Laser freckle removal is not dependent, it does not mean that it will not be possible to have stains again in the future. If the body is in an “unbalanced” state for a long time, do not pay attention to sunscreen and skin care, the spots formed by endocrine factors, do not pay attention to the internal If it is tuned, there is a possibility that it will grow again. Pigmentation equals treatment failure? Pigmentation is a common adverse reaction after laser treatment. The mechanism of its occurrence is currently unclear. Most experts believe that this phenomenon belongs to secondary pigmentation after inflammation, which may be related to individual factors such as excessive sun exposure and dark skin after treatment. It is normal for the pigmentation to appear after laser freckle removal. After treatment, try to avoid sun exposure. Taking vitamin C orally as directed by your doctor can alleviate the pigmentation. It usually subsides after half a year.

Laser “spot” and yellow face woman maker: chloasma

The chloasma, one of the makers of the yellow face, is a type of skin damage on the face. The skin lesions are usually characterized by small spots, light brown to brown, with spots or sesame. The best hair spots are the cheeks and nose bridge (commonly known as “butterfly spots”), which can also spread to the entire face and even the neck, which is one of the most common reasons that affect the appearance of women and a few men. In the previous article, we got to know its etiology, clinical classification and diagnostic criteria, etc. How do we defeat this yellow-faced maker? In fact, there is more than one way to defeat the manufacturer of the yellow face. For the laser, the more familiar method of freckle removal, what effect does it have on chloasma? Let us look down: laser is one of the common treatment methods to solve various pigment spots. It is a non-invasive treatment. It does not require surgery. It has low side effects, short time consumption, and immediate results. It is effective for acne, enlarged pores and many spots. Has a very good therapeutic effect. It is also one of the common treatment methods for chloasma. Its principle is that skin pigments or tissues absorb lasers of a certain wavelength. These lasers of specific wavelengths crush the chloasma pigments deposited on the skin in a very short time and make it Decomposition, while these lasers will also promote the circulation of the skin at the base, with a lower thermal effect on the surrounding skin. The decomposed melasma becomes pigment particles, which will gradually be absorbed by the phagocytes in the body, and the color of the melasma will also lighten. After several treatments, it will usually disappear completely. In most cases, the effect of laser “spot” is good, but the laser is suitable for people. The previous article introduced five kinds of color spots that are common in humans. The types of color spots are different and the causes are different. The effect of laser on them is also The difference. For chloasma, the laser has the effect of removing, but often the effect is not perfect or “comes again after removing”, repeatedly. This is because “the external treatment of plaques and internal treatment of diseases.” The cause of chloasma is mainly related to endocrine disorders. In order to obtain satisfactory results, the treatment of patients’ primary diseases actually plays a decisive role. In addition, pregnant women, people who are allergic to light, and people who are allergic to light-sensitive drugs suffer from chloasma disease, which is also not suitable for laser spot removal. Chloasma is one of the most difficult to remove from all kinds of stains, and its patients need sufficient patience and perseverance and active treatment. If you are troubled by chloasma, you should consult a doctor in time and follow the doctor’s advice, and actively cooperate with the doctor’s treatment to the greatest extent to prevent yourself from “living with a spot” or becoming a yellow-faced woman~

What are the causes of freckles?

What are freckles? Freckles generally appear around 3-5 years of age, and increase in puberty, with the trend of diminishing with age. Most women. Occurs on the face, especially the nose and cheeks, back of the hands, neck and shoulders. The color spots are from the tip of the needle to the large grain of rice, from light brown to dark brown spots, the number is indefinite, ranging from a few sparse to hundreds of dense clusters, isolated and not fused. No conscious symptoms. Insolation can inspire or make it worse, generally light in winter and heavy in summer. What are the causes of freckles? Internal factors 1. Genetic genes: If there are long spots in the parents, the probability of long spots is high. This situation can be determined to a certain extent as the role of genetic genes. 2. Endocrine disorders, female hormones can promote development and metabolism, increase blood circulation, if excessive secretion will stimulate melanocytes to form freckles. 3. Slow metabolism: Freckles can also appear when the liver’s metabolic function is abnormal or ovarian function is reduced. Because the metabolism is not smooth, or the endocrine disorders are in a sensitive state, the pigment problem is exacerbated. 4. Liver dysfunction, the liver has detoxification and metabolic effects, and the nutrient degradation of liver function will not be completely decomposed, so that the skin cannot absorb nutrients and cannot detox! 5. Insufficient qi and blood, bad eating habits, bad living habits! External factors 1. For example, excessive caffeine can stimulate the gastrointestinal tract and cause insomnia, causing mental anxiety, causing melanin molecules to float on the surface of the skin, causing pigmentation, causing dark spots to expand and darken. Acidic food will weaken the blood circulation, affect the new age, suitable for melanin deposition. It is recommended to eat less meat and eat more fruits and vegetables, which will help to brighten the skin! 2. Mental stimulation. When a person is under pressure, the pituitary gland cannot function normally, which causes an increase in adrenal hormones. If you are stressed for a long time, the balance of the body’s metabolism will be destroyed, the nutritional supply required by the skin will tend to be slow, and the pigment mother cells will become active. In turn, it stimulates black cells to produce large amounts of melanin, and pigmentation occurs. 3. Drugs can promote melanin formation or interfere with melanin metabolism and cause melanin deposition (sleeping pills). 4. Ultraviolet rays: When irradiating ultraviolet rays, the human body produces a lot of melanin pigments in the basal layer in order to protect the skin. Therefore, in order to protect the skin, more pigment will accumulate in sensitive areas. Frequently exposed to strong sunlight not only promotes skin aging. 5. Bad cleaning habits: The skin becomes sensitive due to strong cleaning habits, which will stimulate the skin by itself. When the skin is sensitive, in order to protect the skin, the melanocytes will secrete many pigments. When the pigment is excessive, it becomes the cause of freckles.

The beauty crown can be called a porcelain tooth. You need to grind your teeth and wear a custom crown. If you do not pay attention to cleaning in daily life, it may cause toothache, gum inflammation and other problems. Many people will believe in whitening small remedies. Scrubbing your teeth and putting vinegar in your mouth doesn’t work, it’s harmful!   It’s completely useless to wipe your teeth with salt, ground peanuts, orange peel powder! Exogenous coloration refers to the penetration of pigment into the teeth from the outside. For example, the daily diet (coffee, milk tea, strong tea) or the pigment in the mouth penetrates into the teeth, causing the teeth to yellow.  Endogenous coloring   Endogenous coloring refers to the situation where the teeth are discolored from the inside after taking tetracycline drugs or excessive fluoride content in drinking water.   Exogenous coloring can be used for cold light whitening, and endogenous coloring can be used for dental veneer.  Put a higher concentration of peroxide gel on the surface of the tooth to make it enter the interior of the tooth under the excitation of low temperature light, act on the long-chain pigment macromolecules, and remove the pigment through the redox reaction. The veneer is to grind the outermost layer of the tooth thinly, about 0.5mm~1mm, and then get a thin “shell” of cicada wings through a series of procedures such as carving, high-temperature sintering, shaping, dyeing, etc. It is bonded to the surface of the teeth by the doctor to improve the color and shape of the teeth.  Porcelain’s permeability and color are very close to the teeth. It can simulate the texture of the teeth to the greatest extent. Its strength is basically consistent with the strength of the teeth itself. The glue used for bonding is very strong.  Teeth whitening still need to choose the way that suits you, not blindly follow the trend, rational choice is more important!

Five aspects to see whether the treatment of vitiligo is effective

In recent years, there have been more and more people suffering from vitiligo disease, especially in the high incidence season of vitiligo disease, and many vitiligo patients are also suffering from the disease. Vitiligo is different from other skin diseases, not only need to go to the hospital for treatment in time, but also need the patient’s own attention and attention. So how to find out whether the condition is improving during treatment, and how to judge whether a treatment is suitable for yourself? If the following 5 conditions appear in the treatment, stick to it, this treatment is suitable for you! 1. White spots no longer expand and spread if Vitiligo, which is under development, can obviously find that the white spots have stopped spreading after treatment, then it means that your white spots have been stabilized and continue to be treated. After the white spots have stabilized, the pigment has recovered 2. The edges of the white spots have been blurred Unclear to clear and clear We all know that a significant feature of vitiligo in the developing stage is that the edge of the white spot is blurred and may spread to the surroundings. If the edge of the white spot is found to be clear from blurred during the treatment, and There is a ring of pigment around the white spot, then the pigment in the body is slowly being produced, and stick to the treatment, you will see a miracle! 3. There is a deepening of the pigment in the marginal area. In fact, the pigment recovery on the surface of the white spot is not completed at once. Yes, but it takes a process like the depigmentation of the body. The recovery of general pigments will start from the junction of the white spots and normal skin, that is, the depigmentation near the normal skin slowly recovers. Obvious pigment deepening phenomenon, do not worry, slowly treat, the pigment is recovering. 4. There is a kind of pigmentation phenomenon in the white spot area. There is also a case of white spot recovery, which is generally manifested as a pigment island on the surface of the white spot of the skin, that is, a small black spot on the surface of the white spot. Black spots are actually melanin that grows out. 5. The white spots turn red or gradually fade, blur, and shrink inward. When the white spots of the skin turn red or gradually fade, blur, and shrink inward, it is an ideal recovery condition for white spots. Continue to treat, you will see white spots It is getting smaller and smaller, slowly shrinking and recovering until the white spots on the body completely disappear, then the white spots will completely recover! Tips: Vitiligo disease is a skin disease with a longer course and slower recovery, so it is recommended to treat it Be patient, the recovery speed is relatively slow, don’t be too anxious, patient treatment, good daily care, leukoplakia can be recovered!

Refractory pigment therapy

As the name suggests, refractory pigments are pigments that are difficult to cure. Ota nevus, milk coffee stains, Becker nevus, etc. may appear freckles and spots. &nbsp. Milk coffee stains use conventional pigments for stubborn pigments. The treatment effect is not good. Not only is the treatment method different from normal pigment diseases, but also multiple frequency treatments are required before the pigments are completely invisible. Comprehensive treatment with multiple lasers can Relief of many symptoms, such as the well-known Rubystar ruby ​​laser, the American brand Noble EliteMPX. By consulting experienced experts and receiving pigment laser treatment for symptoms, patients can expect greater improvement. &nbsp. The exact number and duration of treatment depends on the location and depth of the pigment, the patient’s skin condition, and the progression of symptoms. Due to the relatively long procedure, the patient’s trust in the treatment team and continued and stable treatment are very important. This is a treatment method that requires patience, but few relapses after treatment are very effective, so satisfaction is high. Because treatment is performed in a way that minimizes pain and does not interfere with daily life, patients will receive satisfactory treatment.

What should I do if I have spot

Our first choice for freckle removal is laser, because the effect is good and the effect is fast. This type of method is also relatively common and has obvious advantages, but do you know? What are the sequelae of improper operation in the process? First: Pigmentation (just do After the laser skin damage is more serious and may cause inflammation, so you must pay attention to care and sunscreen, if it is improper, it will cause pigmentation) Second: depigmentation (this is caused by excessive treatment, laser freckle excessive Blasting melanin, the amount of melanin that is too small, which makes the skin behave less normally) Third: postoperative blisters (mostly due to improper instrument selection) Fourth: facial flushing (caused by not hydrating and moisturizing in time, This tells you crush, you must apply a mask after finishing, do not touch the fresh water after finishing) So, skin management is not a small project, you must go to a regular hospital to find a regular doctor. (The picture shows C10 freckle)

How is vitiligo treatment recovered?

Vitiligo will bring a lot of harm to the patient’s physical and mental aspects, so once the patient is diagnosed, the patient must be actively treated, face the vitiligo with a correct attitude, go to the regular hospital as early as possible to determine the cause through professional inspection, and formulate treatment based on clinical symptoms Program, and pay attention to increasing physical fitness and changing bad eating habits during treatment to regain a healthy body, then, how is vitiligo treatment recovered?    white spots will no longer spread, and normal skin color will appear at the edges, we call it pigment Island, if the patient finds that such symptoms appear on the skin, they must insist on treatment and do a good job of vitiligo care. Slowly these dot-shaped pigment islands will gradually merge and eventually become a pigment band. Generally, pigment islands will appear at the edge of the white spot. As the disease recovers, it slowly moves to the center of the white spot, making the area of ​​the white spot smaller. Some pigment islands spread from the center of the white spot to the surrounding. The most obvious characteristic of the improvement of vitiligo is that the number of white spots decreases and the area becomes smaller. Vitiligo white spots are generally limited to a certain part, and the generalized is spread to systemic white spots, and the area is also very large. In fact, it is easiest to tell whether vitiligo has improved The method is to observe whether the white spots on the patient are reduced. This method may be a bit difficult for localized vitiligo, but this is the simplest method.  When the above two phenomena appear in the treatment, it proves that the condition of vitiligo has improved, and black spots appear on the affected area, which is a sign of melanocyte recovery. When the small black spots completely cover the white spots, the skin of the affected area will return to normal color. It is also recommended that patients should adhere to good living habits after recovery, and it is also very important to continue to consolidate treatment.   Warm reminder: Vitiligo patients must be actively treated, and medicines must be prescribed to achieve good treatment results. Don’t get sick in a hurry, and must adopt scientific and effective treatment methods in a timely manner. Blind treatment will only cost you money and no effect. Therefore, it is the most critical step to choose a regular and professional hospital for the treatment of vitiligo, so as to avoid vitiligo from finding you.

The hair is white and the body is poor.

#微博名医诊室# Patients often ask me online, teacher, I am only xx years old (usually less than thirty), I have not been in love and married, and now my hair is all white. Was it the same day? There are also similar problems. I have poor energy recently, poor sleep quality, low procrastination efficiency, and lack of energy. Is this too much? Immediately following, without exception, will ask, how to quit masturbation? In fact, we can discuss this problem by analogy. What analogy does it have? Take the prostatitis common in urology as an example. For example, a patient came over and told me how to treat my prostate, doctor. You will prescribe two boxes of medicine. I will definitely answer him. Have you checked it and have not tested prostate fluid? I haven’t done B-mode ultrasound. I can tell from the symptoms that I have prostate inflammation? What if the medicine goes wrong? Have you seen? Medicine is very rigorous. To determine whether a problem or disease is caused by a certain disease, in addition to understanding the history, etiology and condition, it is very important to have a basis for judgment, such as the prostatitis test report, white blood cells The value, the number of lecithin bodies, you can tell the patient that you have prostatitis instead of frequent urinary urination and urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urinary urethritis What about benign prostatic hyperplasia? For the same reason, there are many reasons for poor hair and poor health. It cannot be said that it was all caused by masturbation. Although we don’t admire the excessive masturbation of male friends, as a way for the majority of male friends to reasonably and legally vent their desires, reasonable masturbation does not do much harm to the body. Some people will ask here, then I’ve been covered with black silk before I 撸After a while, my hair is white and my body is not good. What’s going on? First of all, what determines the color of the hair is the amount of pigment particles in the hair. The latter is related to the development and growth of the pigment cells in the hair root and nipple. The hair changes from black to black White, generally the pigment cell function of the hair declines. Normal people begin to decline in the pigment cell of the hair from the age of 35. When the pigment is no longer able to produce pigment particles, the hair becomes completely white. Most of the white hair is due to heredity and emotion Anxiety, nervousness, or nutritional deficiencies can be seen from the above. It can be seen that the problems of mental depression and gray hair at the same time are related to lack of nutrition and emotional anxiety, and behind these two, there may be problems with endocrine disorders, The root cause of endocrine disorders is largely due to the fact that masturbation stays up late. As mentioned above, moderate masturbation is desirable. If other symptoms occur, especially when pathological discomfort, you need to go to the hospital for relevant examinations, not Blindly increase the burden of thinking, thinking that it is all caused by masturbation

Do you know why your skin is dark and dark?

Melanocytes are dendritic-like cells that colonize the basal layer of the skin (that is, the junction of the true epidermis), and the pigments it produces are the most important factors that affect skin color. (1) The origin of melanocytes Melanocytes originate from nerves (neuralcrest). Nerve is a transitional structure in the development of vertebrate embryos. Neural crest cells migrate to all parts of the body along the dorsolateral path (between somite and ectoderm) and ventral path (between neural tube and somite), and participate in the generation of craniofacial bones and teeth, skin melanocytes, and endocrine Glands, peripheral nervous system, heart outflow tract and many other structures. Some scholars speculate that the intradermal melanocytes of diseases such as intradermal nevus, Ota nevus, and Ito may be derived from the neural crest cells retained here. (2) Melanocytes and melanosomes are lysosomal membrane-like organelles unique to melanocytes, and are subcellular structures that synthesize and store black. According to its maturity, it can be divided into four stages: 1. A vesicle-like structure with a little irregular fiber structure 2. An ellipsoid with fiber filaments arranged in parallel along the long axis 3. A small amount of melanin is synthesized on the fiber filaments Deposit 4. A large amount of melanin is synthesized, and the fiber filaments are completely covered. In melanocytes, tyrosine is hydroxylated to dopa by the action of tyrosinase, which is converted into indoloquinone by oxidation, decarboxylation and other reactions.Finally, indoloquinone is polymerized into melanin, often with molecular weight Heterogeneous polymers exist. According to the substrate in the reaction process, it can be divided into eumelanin (also known as true melanin or brown/melanin, the substrate is only leucine) and pheomelanin (pheomelanin, also known as red/yellow pigment, substrate) (Lucine, cysteine). At present, it is generally believed that the main reason for the difference in skin color between races is not the amount of melanocytes in the skin, but the maturity of the melanin body and the content and proportion of melanin in the body. (3) Transport of melanin Near the basal layer, a melanocyte transports melanoid bodies from dendrites to the adjacent 36-40 keratins through the interaction of tubulin, kinesin, and dynein in the cytoplasm Inside the cell, such a functional structure is called “epidermalmelanocyte unit”. The melanosomes entering the keratinocytes are transported to the top of the nucleus to form a “protective umbrella”-like structure to reduce the damage of DNA to ultraviolet rays. (4) Degradation of melanin Some scholars believe that cells can phagocytose and degrade melanosomes through the lysosome/autophagosome system. Other scholars believe that lysosomes/autophagosomes can only degrade proteins in the melanin body Fiber, which is powerless to melanin itself, mainly relies on the continuous renewal of the epidermis to take away the pigment particles. (5) Factors affecting melanin metabolism The metabolism of skin melanin is regulated by a very complicated network, and many factors in and outside the body affect it. 1. Heredity and development Heredity and development are the main congenital factors that affect melanin metabolism. Commonly clinically characterized by pigmentation such as freckles, Ota nevus, neurofibromatosis, etc., hypopigmentation such as various types of albinism, mottled disease, nodular sclerosis and so on. 2. Sun exposure is the most significant exogenous factor affecting skin melanin metabolism. Ultraviolet light can promote the expression of various cytokines in keratinocytes and regulate the function of melanocytes in the form of paracrine. Ultraviolet light can also directly affect the function of melanocytes, up-regulate important transcription factors and key enzymes related to melanin synthesis, and promote the formation of dendrites and melanosome transport. 3. Endocrine disorders such as pituitary, adrenal gland, gonadal lesions and even some tumors with secretory function, in vivo estrogen, progesterone, adrenocorticotropic hormone, melatonin, B-LPH and other metabolic disorders, often accompanied by limitations or The skin and mucous membranes of the system are abnormal. 4. Inflammation The effect of inflammation on melanin metabolism is complex and can cause hypopigmentation or hyperpigmentation. 5. Sleep and life rhythm also have an effect on melanin metabolism, but the exact mechanism is unknown. There are reports that it may be related to local circulation, vitamin D3, oxidative stress and so on.

How is vitiligo classified and classified clinically?

&nbsp.&nbsp. The correct classification of vitiligo helps to judge the cause of vitiligo, so as to choose the correct treatment plan. There are many different methods for the classification of vitiligo. After discussion at the First National Academic Symposium in 1993 and the expanded meeting of the members of the Society in 1994, the Pigmentation and Dermatology Group of the National Society of Integrated Traditional Chinese and Western Medicine for Dermatovenereology established the clinical classification criteria for vitiligo. Vitiligo is divided into two types and two types.  Divided type  (1) Common type: It is divided into localized type, sporadic type, generalized type and extremity facial type. Limited type: limited to a single spot or cluster of white spots of different sizes.   scattered hair: scattered white spots, different sizes, can occur in any part of the body, but more symmetrical distribution, the total area does not exceed 50% of the body surface area.  Pan hairstyle: White spots exceed 50% of the total body surface area, and even spread to the whole body, leaving only a few or no normal pigmented skin. It is generally considered to be related to autoimmune abnormalities, mostly developed from the previous two types.   Limb-end facial type: White spots are mainly distributed in the exposed parts of the hands, feet, toes, head and face, and a few can be associated with generalized white spots of the body.   (2) Segment type: The leukoplakia is one or several slices, which are distributed along the skin area innervated by a certain cutaneous nerve segment, generally distributed unilaterally, and are more common in children.   Classification    (1) Complete white spots: The boundary between white spots and normal skin is clear, pure white or porcelain white, the hair in the white spots becomes white or most of them have become white, and there is no pigment regeneration. The melanocytes in the leukoplakia disappeared and the reaction to dihydroxyphenylalanine (dopa) was negative. (2) Incomplete leukoplakia: Incomplete depigmentation in the leukoplakia, with pigment spots left, the hair in the leukoplakia did not turn white or most of them did not turn white, the melanocytes in the leukoplakia decreased, and the reaction to dihydroxyphenylalanine was positive .
