Melasma (also called Chloasma, or the “pregnancy mask” if it occurs during pregnancy) refers to the dark discoloration of facial skin. It usually occurs in women, but a significant proportion of men are also be affected by it. 

The tan, brown patches usually appear on the face and are typically symmetric, with marks on both sides of the face. They can also appear on other parts of the body that are exposed to the sun as the ultraviolet rays affect the cells that control pigment.

Other factors which can trigger melasma are changes in oestrogen and progesterone levels, hormone replacement therapy, genetics, overproduction of MSH (Melanocyte-stimulating Hormone), and allergic reaction to cosmetics or medications. Melasma is more common in people living in the tropical climate due to greater sun exposure.
