Melasma, also known as chloasma or the "mask of pregnancy," is a common skin change characterized by dark, discolored patches, typically appearing on the face during pregnancy.
What it is
This particular type of facial pigmentation is a normal physiological change for many pregnant people. Evidence suggests it affects a significant number of pregnancies, with rates notably higher in those with darker skin tones. Melasma is primarily caused by the hormonal shifts of pregnancy, specifically the increase in estrogen and progesterone, which stimulate melanocytes – the cells responsible for producing pigment in your skin. While hormones are the internal trigger, exposure to ultraviolet (UV) light is understood to be the strongest external factor that can amplify and worsen melasma. Just as your body might experience other hormonal shifts, like Leaking Colostrum later in pregnancy, melasma is another manifestation of these powerful internal changes.
