What causes Melasma?
The exact cause of melasma is not known, but it is thought to be because of pigment-producing cells in the skin (melanocytes) producing too much pigment (melanin). Several factors can contribute to developing melasma, including pregnancy and using hormonal drugs such as birth control pills and hormone replacement. Rarely, other medical problems that affect hormones (such as thyroid problems) may cause melasma, as well as some other medications, such as anti-epileptics.
Exposure to ultraviolet (UV) light from the sun and the use of sun-beds or phototherapy can trigger melasma or make it worse.
Treatment for Melasma
A combination of measures is generally required for melasma treatment. Year-round, lifelong sun protection is the most significant step you can take to helping to prevent or reduce the severity of melasma. However, Melasma treatments fall into the following categories and can be used together:
- Avoid known triggers, such as birth control pills and hormone therapy.
- Avoiding the sun and using sun-blocking creams.
- Procedures like chemical peels, such as the Cosmelan Peel.
- Skin camouflage.
