In the case of human skin, the pigment produced by the body itself is the melanin produced by the melanocytes in the skin. Due to the different shades of melanin, the skin is black or brown in the epidermis, grayish blue in the shallow layer of the dermis, and cyan in the deep layer of the dermis. Endogenous pigments also include lipoproteins, bile pigments, and the like.
The cause of pigmentation, usually stimulated by sunlight, ultraviolet radiation or cosmetics, drugs and other substances, forms a black skin pigmentation, part of which falls off with the stratum corneum; part of which precipitates on the bottom layer and is excreted through the blood circulation. Once dysregulated, pigmentation is formed.
