In recent years, photothermal therapy has become quite popular in China. A casual market survey will reveal that nine out of ten models have probably had a course of treatment in this area. With the rapid development of the beauty market, Chinese people’s acceptance of skin beauty is also growing. Since the market is so hot, all the “experts” also see the opportunity to continue to introduce new, “angel light” “powder light” “white porcelain light “” crystal diamond light “and so on a whole lot of quite attractive light therapy have appeared, see beauty seekers dazzled, every kind of “new light”, would like to try as soon as possible. Just like hearing that an international brand has launched a new bag, causing the beauties to scramble to buy it and get it in their pockets. Try a new light therapy, but also “love of beauty never lag behind” a performance. Beauty seekers have such a consumer mentality, not surprising. However, as a doctor, I am opposed to the idea that people should follow what they say, and I do not like to mislead beauty seekers by blindly recommending new types of programs. Guiding beauty seekers to develop the correct concept of skincare, responsible for their own skin and health, is the most intimate care for beauty seekers. When I meet a candidate who insists on trying a new type of light therapy, I usually remind her that medical aesthetics should not catch up with fads, and not the more trendy and popular light therapy is what your skin needs! All light is not separated from heat, and the doctor’s control of the intensity of heat is the key! At present, with the help of medical instruments to spice up beauty, it seems to have become the mainstream of skin beauty. But so many light therapy instruments, how can beauty seekers distinguish between them? In fact, although the laser instrument is changing day by day, the name of a variety of, but in fact, the field of medical cosmetology can be used in the high safety of the laser instrument are similar, just “major experts” in order to distinguish between the marketing, came up with a lot of new and innovative terminology only. Lasers (laser light) are capable of emitting high energy in a very short period of time and generating heat to cut and suture skin tissues. In the medical field, it was initially used mainly for the treatment of skin tumors, and then gradually used to assist in cosmetic surgery. The effectiveness of laser treatment often depends on the doctor’s accuracy in the operation of the laser instrument and the correct judgment of the wavelength. Imagine how laser and pulsed light, which is a medical grade of light and heat energy, can be administered by someone without medical education. When the high-intensity light, heat production in the need to treat the part, inevitably, around the good skin will also be more or less “affected”, at this time, how to make the horse good, but not to eat the grass next to it, this is to rely on the experience of the professional medical team to judge.
