Melasma is a harmless cosmetic discoloration of the skin, especially of the skin on the face, and is characterized by the presence of dark, irregularly-shaped patches on the skin. The condition is considered to be caused by surges of certain hormones. It is common amongst premenopausal and pregnant women. The patches may disappear on their own, especially for pregnant women on completion of the term of pregnancy. Other kinds of treatment can be ineffective as exposure to the sun may cause them to recur.
HOW IS MELASMA DIAGNOSED?
Genetic factors are important in determining a person's tendency to develop melasma.
