Skin lightening/Melasma
Melasma (muh-LAZ-muh) is a common skin problem. It causes brown to gray-brown patches, usually on the face. Most people get it on their cheeks, bridge of their nose, forehead, chin, and above their upper lip. It also can appear on other parts of the body that get lots of sun, such as the forearms and neck.
Women are far more likely than men to get melasma. It is so common during pregnancy that melasma is sometimes called "the mask of pregnancy." Hormones seem to trigger melasma.
