Melanin shields the nucleus from damage by ultraviolet radiation. It keeps this radiation from damaging the skin and DNA. It also gives color to your skin, hair, and irises. Melanin is a pigment which gives characteristic color to skin. Its main role is to absorb harmful UV radiations and protect our skin cells from damage. It determines the color of your skin. Melanin colors hair, skin, eyes, feathers, etc.
