Melasma Overview
Melasma is a skin condition characterized by dark, irregular patches on the skin, usually on the face. An overproduction of melanin, the pigment responsible for skin color, causes these patches. While melasma poses no health risks, it can significantly impact one’s appearance and confidence. It often occurs more frequently in women, especially during pregnancy, earning it the nickname “the mask of pregnancy.” It is still unclear what triggers melasma, but several factors may play a role in its development, including hormone changes, prolonged exposure to sunlight, and genetic predisposition.
Causes of Melasma
The precise causes of melasma are multifactorial, with hormonal fluctuations being a key trigger. An overproduction of melanin can contribute to the development of melasma. This excess melanin can be triggered by factors such as pregnancy, taking birth control pills, and undergoing hormone replacement therapy. Sun exposure is another crucial factor, as ultraviolet (UV) rays stimulate melanocytes, the cells responsible for melanin production. Genetics also plays a role, as individuals with a family history of melasma are prone to developing the condition. Hormonal and genetic factors can interact with external triggers, exacerbating the likelihood of melasma development.
