Melanocytes can synthesize and secrete melanin, so they are gland cells. However, the biosynthesis of melanin is very complicated, which is formed by tyrosine-tyrosinase reaction in chromosomes (immature melanin).
Substances that change the pathway of melanin production, such as glutathione kojic acid, arbutin and vitamin C, can also be used to remove spots. The effective components that can inhibit the formation of melanocytes are chloroquine, indomethacin, vitamin C, 9- carotene, green tea, kojic acid, melanin, dark plum, cinnamon, licorice oil and soluble extracts.
