Web1. Introduction. The human skin is an important organ in the body and a source of various cells, including melanocytes that residue on the basal layer of epidermis [].The main feature of melanocytes is the production of melanin in special organs-melanosomes during a physiological process, called melanogenesis. WebThe epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss..
