Often cheeks, upper lip, the bridge of the nose and forehead are the most affected areas.
Melasma can usually be associated with a change in contraceptive pill, IUD or hormone patch. It can also be associated with higher levels of Oestrogen at certain times during the menstrual cycle and he way the skin then reacts to sunlight. Only 10% of those affected are men.
Chloasma is usually related to pregnancy and often referred to as the ‘mask of pregnancy’. It can develop on the face and other body areas.
