What is the primary function of melanocytes in the skin?

The primary function of melanocytes in the skin is to produce melanin. Melanin is the pigment responsible for the color of skin, hair, and eyes, and it plays a crucial role in protecting the skin from the harmful effects of ultraviolet (UV) radiation. By absorbing UV light, melanin helps to prevent DNA damage in skin cells, which can lead to skin cancer. Melanocytes are located primarily in the lower layer of the epidermis and are vital for maintaining skin tone and providing a natural defense against sun exposure. This melanin production is essential for both aesthetic and protective functions in the skin.
