What is melasma?

Can you please tell me what is melasma? I am a 26 year old female who is 14 weeks pregnant.

Melasma is a skin disorder and is also known as ‘chloasma’ or ‘mask of pregnancy’. Melasma is associated with dark patches of skin which gradually develop on cheeks, forehead, nose, and upper lip. Melasma is more common in women and is associated with pregnancy and certain medications that contain hormones. Melasma seems to develop in about 60% of pregnant women but can also occur in men. Melasma is most common in Asians and in those with dark skin complexion.It is not a disease and in 99.99999% of cases, the condition resolves on its own. This means - please do not be a sucker and fall for the fradulent therapies that are being offered.
