It consists of symmetric, well-defined, light to dark brown patches. The most common sites are on the malar cheek, lateral forehead, upper cutaneous lip, and mandible. Factors associated with accentuation of melasma include sunlight exposure, pregnancy (often called “the mask of pregnancy”), and oral contraceptives.
