Melanin synthesis and metabolism are closely related to melanocytes. Whitening skin care products generally inhibit melanin production and accelerate melanin metabolism through various links of melanocyte metabolism, so as to achieve the purpose of whitening.

1. The common whitening ingredients are ellagic acid(Pomegranate Peel Extract), palmitoylethanolamide (PEA, 98% up) and nonapeptide-1 (99% up by HPLC), which affect the formation of melanocytes;

3. Nicotinamide, fruit acid, salicylic acid, all-trans-retinal and their derivatives block melanin transmission and accelerate melanin metabolism.

4. Some products with anti-inflammatory effects, such as red myrrh alcohol, glycyrrhizic acid and Palmitoylethanolamide (PEA) can play an auxiliary whitening role by reducing inflammatory reaction.

5. In addition, different active ingredients are often compounded, which can play a synergistic role and improve the whitening effect. For example, adding guaia zulene or copper peptide (GHK-Cu) has the function of repairing skin; Adding sodium hyaluronate has the function of moisturizing; The addition ofSuperoxide dismutase RH-Cu,Zn SOD has antioxidant function.
