Pigmentation is caused by the synthesis and distribution of melanin, which is formed by a series of chemical reactions of tyrosine. Melanin usually exists in the form of polymerization. The mechanism of melanin synthesis involves various enzymes, mainly tyrosinase and tyrosine-related protein.

In general, proper melanin can protect against ultraviolet radiation, but hyperpigmentation can cause serious aesthetic problems. Studies have shown that some peptides can be transported to human skin and have a skin whitening effect. For example, nonapeptide-1 has the potential to significantly whiten the skin.
