TY - CHAP M1 - Book, Section TI - Overview of Melanin Production A1 - Baumann, Leslie Y1 - 2015 N1 - T2 - Cosmeceuticals and Cosmetic Ingredients AB - Melanin production occurs inside the melanosomes located in the melanocytes. The process of melanin synthesis begins with the hydroxylation of tyrosine to 3,4-dihydroxyphenylalanine (DOPA) using the enzyme tyrosinase (Figure 33-1).1 Two types of melanin are produced: eumelanin and pheomelanin. The relative amounts of these two forms of melanin determine hair color and skin tone. Individuals with darker skin tones have mostly eumelanin and a lower level of pheomelanin, while the opposite is true in people with a light skin color.
