Genetically, this skin type is different from Caucasian skin through a network of elastic fibres and denser collagen. Melamine dispersion through all layers of the epidermis and a lipid film richer in lipids is a characteristic of Black skin.
More toned and better protected, it ages slower than lighter skin. Well suited in its original environment, it becomes more vulnerable in temperate climates or becomes dehydrated, causes dry skin, and gives a greyish appearance to the skin.
Acne is more prevalent, the secretion of sebum and shedding increases, the dead cells persist and obstruct the pores, creating pimples. People with this skin type can use the same treatment as oily skin by increasing the frequency of exfoliation.
