(aka "Mask of Pregnancy")
Higher levels of Estrogen and Progesterone can cause Melasma -- the dark blotches that look like a mask mostly on the cheeks, chin and lips.
Melasma is very common, but hard to treat during pregnancy except with a concealer, since drugs would be harmful to the baby.
It fades after delivery, but in the meantime, avoid exposure to the sun and use a sunscreen everyday with at least a 30 SPF - even in the winter months. You can still get rays through the clouds.
