One melanocyte is therefore in contact with about 36 keratinocytes; together they form the so-called epidermal melanin unit. Melanocytes are most commonly in epidermis and follicle. Melanin involves eumelanin and pheomelanin, if s synthesized through a series of stages in which the enzyme tyrosinase acts on melanin precursors to produce the densely pigmented g...
