Asked by | 28th Dec, 2012, 02:27: PM
The primary function of melanin is to protect the skin and underlying tissue from sun damage. The more melanin a person has the more harmful ultraviolet radiation from the sun he can block.
In humans, melanin present in the skin is responsible for different skin tone and the constituent of freckles.
