Will my skin turn black if I use the red and blue beauty device?,importing beauty device manufacture

　　Many customers are more concerned about whether red and blue acne treatment will make the skin darker? Many people say that it will not cause the skin to turn black. There are a lot of reasons. However, I investigated and found that after some people were exposed to red and blue light, their skin turned black. In the rigorous attitude of popular science, I checked the relevant information and found that it is indeed possible to cause the skin to darken.

　　Scientific research [Clinical and histological effects of blue light on normal skin] shows that blue light does have the risk of inducing skin pigmentation, that is, melanocytes produce excessive melanin and deposit in epidermal keratinocytes, causing skin to darken.

　　The research theoretically pointed out that the wavelength of blue light is close to that of long-wave ultraviolet UVA, which can induce biological effects related to UVA radiation. At the same time, it is confirmed from histology that the skin irradiated by 420nm blue light has very slight pigmentation, but the proportion is small, and it will only produce short-term melanin formation without causing cell apoptosis (that is, there will be no major problems) . And after the blue light irradiation is stopped, the production of melanocytes is rapidly reduced, and melanin deposition is reduced.

　　Therefore, both theoretical studies and experimental results indicate that short-wave blue light has the risk of "tanning" the skin, which is similar to ultraviolet tanning; however, the occurrence of this melanin pigmentation phenomenon is not high, and after the blue light irradiation is stopped, it will gradually recover, so do not worry too much.

　　In fact, compared to laser and intense pulsed light, LED blue light used to treat acne has a milder effect, and the risk of melanin deposits on the surface of the skin is not so high.

　　Having said so much, you may already understand. Red and blue light have the risk of slightly darkening the skin, but the possibility is not particularly high, and it can be recovered. Eat more vegetables and fruits rich in vitamins.
