- Melanocytes produce melanin which is the pigment that gives skin its normal color, and are located in the bottom section of the epidermis. To help protect the deeper layers of the skin, melanocytes produce more melanin when exposed to the sun.
Ultraviolet light () infrared light and other potential causes:
DNA damage in skin cells and is used in the major portion of the light of the sun in the solarium ultraviolet light (UV-UV) radiation comes from. However, under normal conditions of sun exposure skin cancer that occurs on skin that is not exposed to the sun's rays do not explain.
