Melanin protects from :-Melanin is a dark brown pigment produced by melanocytes in the skin.
It absorbs harmful ultraviolet (UV) radiation of sunlight and prevents it from damaging the DNA of deeper skin cells, which could otherwise cause sunburn and skin cancer.
That is why people living in tropical regions with strong sunlight have more melanin (darker skin), and the skin tans on exposure to the sun.
So melanin protects from U.V. rays.
