Melasma is an acquired irregular brown or greyish-brown facial pigmentation that primarily affects women and often those with darker complexions. The dark, irregular pigmented areas appear on the face and occasionally on the neck. The precise cause of melasma is unknown, but the following factors have been known to contribute: genetics, sun exposure, pregnancy, oral contraceptives, cosmetics, and drugs containing phototoxic agents such as antiseizure medications. Treatment can be done with topical agents as well as lasers.
