What Causes Melasma?
Melasma occurs due to an overproduction of melanin, the pigment responsible for skin color. This is often triggered by hormonal fluctuations such as those during pregnancy, pre-menopause, or while using birth control pills. It tends to affect women more frequently, especially those with medium to darker skin tones. Sun exposure plays a major role in worsening melasma, as UV rays stimulate the pigment-producing cells in the skin. Other contributing factors include a genetic tendency, heat exposure, and the use of certain medications or cosmetics that increase skin sensitivity. In some cases, inflammation or irritation of the skin can also trigger or aggravate melasma.
