The specific cause of Melasma is still unknown, but it is reported to be because of the pigment-producing cells in the skin (melanocytes) producing too much pigment (melanin).
Factors that can contribute to developing melasma, include;
- Birth Control Pills
- Medical problems that affect hormones
- Certain medications medications such as anti-epileptics.
- Exposure to ultraviolet (UV) light
- Use of sun-beds
Melasma is more commonly developed by women, particularly during pregnancy where up to 50% of women can be affected. It is also more common in people of colour and those who tan very quickly. Melasma is not hereditary but it is more common in people with a family history of the condition.
