Melasma is a very common patchy brown, tan, or blue-gray facial skin discoloration, primarily seen on the upper cheeks, lip, forehead and chin of women 20–50 years of age. Uncontrolled sunlight exposure is considered the leading cause of melasma, especially in individuals with a genetic predisposition to this condition. Melasma is most common among pregnant women, called Chloasma, especially those of Latin and Asian descents. People with olive or darker skin, such as Hispanic, Asian, and Middle Eastern individuals, have higher incidences of melasma.
