Chloasma, also known as Melasma is a tan or dark skin discoloration. Although it can affect anyone, melasma is particularly common in women, especially pregnant women and those who are taking oral or patch contraceptives or hormone replacement therapy (HRT) medications.
The symptoms of Chloasma are dark, irregular well demarcated hyperpigmented macules to patches commonly found on the upper cheek, nose, lips, upper lip, and forehead. For this reason they are sometimes called “the mask of pregnancy”.
It does not cause any other symptoms beyond the cosmetic discoloration. It is also common in pre-menopausal women. It is thought to be enhanced by surges in certain hormones.
