Frequently Asked Questions About Melasma

What causes melasma?

Melasma is a common skin disorder. Though it can affect anyone, women with darker skin tones (especially Hispanic, Asian, Indian, and Middle Eastern) are at greatest risk. Melasma can be associated with the female hormones estrogen and progesterone. It is especially common in pregnant women, women who are taking oral contraceptives, and women taking hormone replacement therapy during menopause. The use of cosmetics is associated with melasma but the relationship between the two is not understood. Sun exposure is strongly associated with melasma.
