Melasma

Melasma (muh-LAZ-muh) is a darkening of skin on the face. It's sometimes called the mask of pregnancy. Dark patches usually appear on the forehead and cheeks. Melasma can get worse after time in the sun.

Melasma often affects:

  • Black, Asian and Hispanic people.
  • People who use birth control pills or hormone therapy.
  • People in their second or third trimester of pregnancy.

Melasma might fade after the birth of a baby, during the winter months or when a person stops taking birth control pills. But melasma also can last for years.
