Melanin: The pigment that gives human skin, hair, and eyes their color. Dark-skinned people have more melanin in their skin than light-skinned people have. Melanin is produced by cells called melanocytes. It provides some protection again skin damage from the sun, and the melanocytes increase their production of melanin in response to sun exposure. Freckles, which occur in people of all races, are small, concentrated areas of increased melanin production.
Melanin protects our body from the sunâs ultraviolet radiation, and melanoma. More melanin presence in the skin makes the skin appear black, and less melanin will make the skin appear less black. White people have very little melanin synthesized by their skin.
