Cosmetic grade nicotinamide is a small molecule that can be absorbed directly by cells and plays a key role in maintaining skin energy balance, restoring cell energy and accelerating collagen synthesis.
Cosmetic grade nicotinamide reduces melanin deposition due to low skin oil and thin cuticle.
Cosmetic grade nicotinamide can not only inhibit the generation of melanin, but also act on the generated melanin, effectively inhibit about 35% ~ 40% of melanocytes to keratinocyte transfer, thus reducing the generation of melanin.
