Signs and symptoms of melasma include brown or gray-brown patches on the cheeks, nose, upper lip, chin, and/or forehead. Occasionally, the darkened areas can appear in other parts of the body such as the forearms, neck, or shoulders. Melasma is not painful and does not pose any health risks.
Causes of melasma
The exact cause of melasma is unknown, but certain triggers for its development include use of birth control pills, sun exposure, and certain skin care products. Increases in hormone levels during pregnancy often trigger the condition, which is termed chloasma or "mask of pregnancy."
