Nicotinamide is a derivative of vitamin B3, also known as vitamin PP, which has been recognized as a skin anti-aging factor in the field of cosmetic dermatology. Nicotinamide is a water-soluble substance with the characteristics of solution stability and photostability. It is widely used in medical treatment, skin care and other fields. It can play the role of oil control, anti-inflammatory, whitening, moisturizing, anti-aging and so on.
The whitening principle of nicotinamide is mainly realized from two aspects. One is that nicotinamide can inhibit the generation of melanin, and the other is that it can reduce the melanin already produced.
Skin cells every day need enough energy to complete the new cells, collagen synthesis, fat and protein, DNA synthesis routine of physiological function, nicotinamide can maintain the energy balance of skin, recover energy cells, accelerate metabolism, promote the melanin cutin cell falls off, so as to promote the skin whitening.
On the other hand, due to the transfer of melanin to keratinocytes, therefore, the skin becomes dark, and nicotinamide can act on the melanin that has been produced, reduce its transfer to surface cells, can effectively inhibit 35%~40% of melanin transfer to keratinocytes, reduce pigmentation. Clinical trials have shown that applying a moisturizer containing nicotinamide in moderation over a period of time can significantly reduce the area and number of brown spots on the skin, with changes visible to the naked eye before and after use.
The whitening effect of nicotinamide is an important reason why it is known to us. The production and application of nicotinamide have experienced many years of research, and have been well improved and expanded in the production process and application fields. As a cost-effective skin care raw material and pharmaceutical raw material, its market demand still maintains a good development trend.
