Nicotinamide has the effect of whitening the skin by speeding up metabolism and speeding up the exfoliation of the keratin-containing melanocytes. Nicotinamide has a small molecular weight, which can be directly absorbed by epidermal cells, stimulate the vitality of some of the weak cells, promote collagen synthesis, and prevent excessive deposition of melanin, so as to play a whitening role.
Nicotinamide has an anti-aging effect, it can promote the synthesis of epidermal protein, enhance the defense ability of the skin, increase the water content of the skin, and reduce facial wrinkles, dark yellow, spots, and other skin problems, therefore, nicotinamide often appears in some anti-aging skin care products.
Nicotinamide has the effect of controlling oil and shrinking pores. When the content of nicotinamide in skin care products reaches 2%, it can reduce the production of fatty acids and triglycerides in the sebum secreted by the skin, thus achieving the effect of oil control and oil removal, preventing the sebum from clogging the pores, and helping to shrink the pores after oil control.
