The whitening effect of vitamin B3 is manifested in three ways. 1, unlike previous whitening that only focuses on inhibiting the production of melanin, vitamin B3 can act on melanin that has already been produced. 2, accelerate skin metabolism and promote the exfoliation of melanin-containing keratinocytes. 3, promote the synthesis of epidermal protein and enhance skin hydration, thereby improving skin texture.
