Everyone knows that whitening injection can whiten the skin, so why does this whitening injection whiten the skin? I believe many beauty lovers want to know the answer. Let's take a look at the information brought by Bian Xiao: Bian Xiao learned from Xuzhou plastic surgery experts that the reason for pigmentation on his face is that human skin constantly metabolizes all kinds of garbage every day. If the secretion cycle in the body is not smooth, melanocytes produce too much melanin and deposit too much in epidermal keratinocytes, pigmentation will occur. Why does the skin turn white after injection of whitening needle? If melanin does not accumulate and metabolism is smooth, tyrosinase is needed. If you combine this enzyme, you cannot produce melanin. Amino acid, the effective component in whitening injection, has antioxidant and reducing effects, which can lock the activity of tyrosinase and make it ineffective. Thus, the process of melanin consumption and synthesis stops. Why does the skin turn white after injection of whitening needle? Whitening needle not only contains amino acids, but also contains a lot of nutrients needed by human body, such as decomposing plain color for dark yellow skin and supplementing skin nutrition. It is the most ideal and safest whitening method now. I believe that through the small series of articles, you have a certain understanding of whitening needles.
