Thin and Thick Skin with Melanin | Skin - Histology Guide
Melanocytes (#1 and #2) - melanin-producing cells located in the stratum basale. Paradoxically, melanocytes are unpigmented because they do not store melanin. Melanin is transferred to other keratinocytes in membrane-bound organelles (melanosomes).

Melanin is made by melanocytes. Up to 8% (1 in every 5 to 10 cells) in the epidermis is a melanocyte (melano means black) make up 8% of the epidermal cells. Melanocytes make the pigment called melanin. Tyrosine is converted into dihydroxyphenylalanine (DOPA) which is then polymerised into melanin.
