Qin Lan also said that she often does some skin care projects such as lasers. Judging from the needs of stars, the frequency of doing medical beauty is estimated to be much more frequent than that of ordinary people. But so often doing medical beauty, don't stars have the problem of "anti-black"? Jelly Lin laser, comment below, someone is asking what to do with the color after laser. As for laser and photon projects, children's boots that may have taken various courses online will be fooled by the word "anti-black".
What? I want to freckle and whiten, will the result be black? Tell you, yes, and there are not only photoelectric projects, but also other projects, skin care products. It's a little crazy to hear this conclusion, but don't worry, after the "anti-black" of the third master in the popular science series, you will find that anti-black does not mean treatment failure, and it is not so terrible. Why anti-black?
The most frequent occurrence of "anti-black" is the topic related to laser/photon projects. Let's start with the principle of this project. Whether it is laser or photon, its mechanism of action is to beat some "pigments" in the skin with light, such as making melanin and red hemoglobin; Or take water as the target to remove epidermis and improve wrinkles and acne. No matter what the target is, the light will provide energy to the target after entering the skin. Using this heat energy, we can "burn" melanin, hemoglobin, epidermis, etc., which is necessary for treatment. However, this kind of heat will also stimulate the inside of the skin to a certain extent, and then cause skin inflammation.
