Causes of Human Skin Hyperpigmentation. The color of human skin is due primarily to the production of melanin by specialized cells in the skin called melanocytes. Melanin produced by these cells both absorbs and scatters UV radiation and thus protects skin from the damaging and mutagenic effects of the solar radiation.
Hyperpigmentation can be caused by sun damage, inflammation, or other skin injuries, including those related to acne vulgaris. : 854 People with darker skin tones are more prone to hyperpigmentation, especially with excess sun exposure. Many forms of hyperpigmentation are caused by an excess production of melanin. Hyperpigmentation can be diffuse or focal, affecting such areas as the face and the back of the hands. Melanin is produced by melanocytes at the lower layer of the epidermis. Melanin is a class of pigment responsible for producing colour in the body in places such as the eyes, skin, and hair.
