Dermal melanin is produced by melanocytes, which are found in the stratum basale of the epidermis.
Melanin is a pigment that is produced by cells known as melanocytes in the skin of most animals. It comes in two basic forms: eumelanin (brownish color) and pheomelanin (reddish-brown color). The production of melanin is affected by UV exposure, genetic make-up, size of melanocytes, and disease conditions.
