Also known as chloasma, melasma is a condition where larger patches of hyperpigmentation develop mainly on the face.
Although it can affect both men and women, melasma is most common in women and is thought to be triggered by changes in hormone levels. Melasma occurs in 10–15 percent of pregnant women and in 10–25 percent of women taking oral contraceptives 1 and is sometimes referred to as “the mask of pregnancy”.
