In nicotinamide and cosmetics products, through use, it can block the small melanin body that is tried to keratinocyte transportation through the keratin layer of the muscle bottom, thereby inhibiting the precipitation of melanin, but this will not affect the cheese Actinase activity and cell proliferation. It hinders the cell signal channel between keratinocytes and melanocytes, inhibits melanin production, and can also act on the melanin that has been generated, reducing melanin transfer to surface cells, and thereby reducing melanin precipitation.
The mechanism of whitening of nicotinamide is roughly the same. As a component of the whitening effect, nicotinamide is generally 2%to 5%in skin care products. The use effect of this amount is ideal. If the concentration is too low, it will affect the play of its role. If the concentration is too high, it is easy to cause skin allergies. Therefore, when buying the corresponding nicotinamide skin care products, it is recommended to pay attention to the concentration, you can try it in a small area first.
