Melasma is a common skin problem. It is also called chloasma, or the “mask of pregnancy” when it occurs in pregnant women. While men can develop melasma, 90 percent of individuals with the condition are women, according to the American Academy of Dermatology.
The condition causes patches of dark discoloration to occur on your skin. These patches are darker than your typical skin color. While the majority of cases occur on the face, other areas of your body that are often exposed to sun can also develop melasma. When it occurs on the face, it is typically symmetrical, with marks on both sides of the face matching.
