How to control the amount of niacinamide in skincare products?

Cosmetic grade nicotinamide has whitening, moisturizing, oil control, anti-aging, and other effects. It can be said that it is a powerful ingredient that helps us comprehensively improve a variety of skin problems. After years of experiments and tests on the effect of cosmetic grade niacinamide, we can find that it has an obvious effect in delaying skin aging and inhibiting melanin deposition. Many of us regard cosmetic grade niacinamide as a magic beauty ingredient or whitening artifact.

Why cosmetic grade niacinamide can achieve a whitening effect? Cosmetic grade niacinamide blocks the transfer of melanin to surface cells, accelerates the exfoliation of the keratin containing melanin, and desalinates the yellowing of proteins after glycation, to achieve the ideal whitening effect. However, in the process of use, we will also find that the concentration of cosmetic grade niacinamide and the overall formula of the product will affect its use effect. From the point of view of the concentration of the use, if the concentration is less than 2%, it is unable to achieve the ideal use effect. The concentration of cosmetic grade niacinamide in skin care products and cosmetics is mainly 2%~5%. Higher than 5% increases the risk of skin irritation.
