Melasma is a common skin disorder. It most often appears in young women with brownish skin tone, but it can affect anyone.
Melasma is often associated with the female hormones estrogen and progesterone. It is common in:
- Pregnant women
- Women taking birth control pills (oral contraceptives)
- Women taking hormone replacement therapy (HRT) during menopause.
Being in the sun makes melasma more likely to develop. The problem is more common in tropical climates.
