How to treat acne?

Acne pits after acne are usually atrophic scars. Long ago when medical technology was not very developed, there was no better way except for the whole skin resurfacing, but in recent years we have to thank the invention of fractional laser , The effect of fractional laser on acne pits can be said to have been very satisfied. Fractional laser is divided into exfoliative lattice and non-exfoliative lattice. Exfoliative lattice laser is generally stronger than non-exfoliative. In Qianbo’s previous cases, fractional laser treatment has a probability of 13% after 5 times. Very satisfied, about 40% of the improvement is obvious, especially for very superficial pits, the satisfaction is even higher. As for the appearance of pigmentation, it is easy to cause the risk of pigmentation if we Asian yellow people undergo traumatic laser treatment, but in summary, the appearance rate of pigmentation is about 16%. If the skin condition before surgery is not good, for example It is easier to induce hyperpigmentation after sun exposure, allergies, dryness, etc. before treatment. However, the correct and proper nursing method will greatly reduce the probability of the appearance of the pigmentation, and the pigmentation will basically gradually fade over time. The main purpose of acne pits is to improve as much as possible. Experience suggests that increasing the number of treatments may be more effective, but the time and money costs also increase.

4 points are necessary for hair growth after hair transplantation

Hello, everyone, I am Liu Changchun, a hair doctor~ Everyone knows that hair transplanting is an effective way to treat hair loss, but if you want your hair to grow well, it is not enough to know that! Also know the following 4 points! First, the design before the operation of a hair transplant surgery can be done well, preoperative preparation is very important. Different people have different requirements on the hairline. Preoperative design needs to combine personal realities and aesthetic requirements. It is not the lower the better. 2. Whether the hair follicle resources are sufficient and the hair transplant area of ​​the hair friends and the available hair follicle resources are the decisive factors that determine the effect of hair transplantation. If the area of ​​hair loss is particularly large, the number of hair follicles will be in a state of “in short supply”, and the effect of hair transplantation will not reach the ideal state of the patient. Third, the doctor’s surgical technique and experience The doctor with rich surgical experience will protect the original hair from harm as much as possible during the hair removal process, and will be extra careful and careful when processing and classifying the hair follicle resources. Skilled instrument use will make the surgical effect more secure. Lattice dot matrix hair transplantation technology is different from traditional tweezers hair transplantation. lattice dot matrix hair transplantation is to place the hair follicle in the transplantation needle and implant the hair follicle through the transplantation needle. Compared with the traditional hair transplanting method using jewel knives and tweezers, the advantages of small hair trauma, high density and natural direction are widely recognized in the industry, and are recommended by the International Hair Transplant Congress (ISHRS). In China, the Barley Hair Transplant Chain Hospital is the hair transplant institution that preferentially introduces the technology. The technology was upgraded and improved in 2009, 2010, 2011, and 2018, respectively, and corresponding national patents were obtained. Lattice lattice hair transplant is one of the current mainstream hair transplant technology in China. Fourth, the degree of postoperative care How effective the hair transplant surgery is, in addition to seeing the doctor’s skills and techniques, postoperative care can not be ignored. Good postoperative care not only helps recovery of surgical wounds, but also shortens the recovery period to a certain extent.

Acne pit, about 5 years, want to get effective treatment

Patient’s question: Acne pit, about 5 years, if you want to get effective treatment, a friend recommended to come to consult, hope to get a face consultation, get good treatment effect Wu Yule (Deputy Chief Physician): Hello, from the picture, you are on the cheek The acne pits with deep distribution are concave acne scars. According to the conventional treatment, erbium laser grinding plus dot matrix laser and photon skin rejuvenation are used. However, because the acne pit is relatively deep, it may require 2 to 3 treatments, or a point-like skin transplant, which can maintain the original elasticity and color of the skin to the maximum extent. Each course of treatment takes about three months before the acne pits have enough time to grow, so that the bottom of the scar grows flat. Because the sunken skin is not flattened by laser, but flat. What specific treatment plan and how many treatment courses are needed? After the outpatient consultation, it needs to be determined in person. For other treatment methods, if acid peeling, needle rolling treatment, filling or subcutaneous separation, the effect is not obvious. The simple grinding method does not have the good effect of erbium laser grinding plus dot matrix laser.
