Melasma, also known as Chloasma, is tan or dark skin discoloration. While it can affect anyone, it is much more common in pregnant women, and is caused by hormonal changes in the body. Thankfully, Melasma usually reverses itself once the hormone levels go back to normal.
An Overview of Melasma
Melasma spots are irregularly shaped dark patches most commonly found on the cheeks, nose, lips and forehead. It causes skin discoloration, and will fade away over time. Since it’s caused by hormonal changes, it is most common in pregnant women, those taking hormone replacement therapy and pre-menopausal women. Progesterone and estrogen can cause the skin’s melanin production to change, resulting in increased production and thus the change in skin color. It is more common in light-brown skinned women living in areas with intense sun exposure. A pre-existing thyroid disease can increase the incidence of Melasma, as can an allergic reaction to medication or cosmetics. If you aren’t pregnant, or feel that there should be no reason for hormonal changes in your body, you can talk to your dermatologist to understand what is causing it.
