Melasma is a common skin condition characterized by the development of brown or gray-brown patches on the face, particularly on the cheeks, forehead, nose, upper lip, and chin. These patches are usually symmetrical and have a well-defined border.

Melasma typically affects women more than men and is most commonly seen in individuals with darker skin types, particularly those with Fitzpatrick skin types III to VI. The exact cause of melasma is not fully understood, but it is thought to be related to the overproduction of melanin (the pigment that gives color to the skin) by the melanocytes in the skin.

The development of melasma is associated with a number of risk factors, including hormonal changes (such as during pregnancy or while taking birth control pills), sun exposure, and certain medications (such as anti-seizure drugs and some cosmetics).

Treatment options for melasma include topical medications (such as hydroquinone, tretinoin, and corticosteroids), chemical peels, and laser therapy. However, melasma can be challenging to treat, and it may recur even after successful treatment. Sun protection, including the use of sunscreen and wearing protective clothing, is also important in preventing and managing melasma.
