Answer:
Melanin is a skin pigment.
Explanation:
Melanin is a skin pigment that is present in the bottom layer of the skin's epidermis. Melanin may help protect the skin from Ultraviolet rays. Increasing in the concentration of melanin may block processes in the body that lead to skin cancer. Ultraviolet light kills cells by damaging their DNA. The light starts a reaction between two molecules of thymine which is one of the bases that is responsible for the formation of DNA molecule. Melanin has the ability to absorb Ultraviolet light which automatically protects skin cells. The presence of melanin in the skin decreases the rate of skin cancer diseases around the world.
