Skin Lightening Mechanism

Skin color is mainly determined by the amount of melanin in the skin. Melanin is synthesized in melanocytes. Normally, melanocytes are present in the basal layer of the epidermis. In melanocytes, melanin is combined with a protein matrix to form melanosomes. In melanin granules, tyrosinase converts tyrosine into normal melanin (eumelanin) or brown melanin (pheomelanin).

Skin lightening agents can block or even reverse melanin biosynthesis. Therefore, it can be used to lighten or lighten human skin. Skin lightening agents can also be used to treat localized hyperpigmentation or spots due to excessive local melanin synthesis or uneven distribution.
