Darkening of Skin
Skin | Dermatology | Darkening of Skin (Symptom)
Hyperpigmentation it is represented first of all by a cosmetic problem that can be covered with makeup, although in some cases it may be a sign of an underlying medical problem.
Hyperpigmentation can be caused by sun damage, inflammation or other skin lesions, including those associated with acne.
There are many forms of hyperpigmentation that are caused by excessive melanin production. This condition can be diffused or focal, affecting areas like the face and back of hands. Melanin is produced by melanocytes in the lower layer of the epidermis. Melanin is a class of pigment responsible for colour production in the body, in places such as the eyes, skin and hair. As the body ages, the distribution of melanocytes becomes less diffuse and regulation less controlled by the body.
