Hyperpigmentation may be caused by sun damage, inflammation, or other skin injuries, including those related to acne vulgaris. 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 color in the body in places such as the eyes, skin, and hair. As the body ages, melanocyte distribution becomes less diffuse and its regulation less controlled by the body.
Another form of hyperpigmentation is post inflammatory hyperpigmentation. These are dark and discolored spots that appear on your skin following acne that has healed.Hyperpigmentation is treated with the Skin Classic and varies with individual cases.
