Melasma is a common skin condition. Causing brown to gray–brown patches, melasma usually appears on the face. The cheeks, bridge of nose, forehead, chin, and upper lip are places where melasma is likely to form. It also can develop on the forearms and neck.
Most melasma occurs in women. Only 10% of those affected are men. People with darker skin tones, including those of Latin, Asian, Indian, Middle Eastern, Mediterranean, and North African descent, tend to have melasma more than others.
