Pigmentation by sunburn. View of dark patches of skin on the back of a 35 year-old man caused by childhood sunburn. Skin is coloured by a pigment known as melanin produced by melanocyte cells in the skin. Lighter-skinned people produce less melanin that darker skinned people. In cases of severe sunburn,the pigmentation of the burned skin can be permanently altered by the effects of overexposure to sunlight | |
