Definition
A melanocyte is a specialized skin cell that produces melanin, the pigment responsible for skin, hair, and eye color. These cells are located in the epidermis and hair follicles. Melanin protects the skin from harmful UV radiation. Different levels of melanin production result in varying skin tones. Melanocytes transfer melanin to keratinocytes, the predominant cells in the epidermis. Think of them as the body's natural sunscreen producers.
