Is it safe to wear makeup in pregnancy?

Probably: Yes, it's probably safe, especially if you're buying conventional products sold in stores. On the other hand, no testing of the sort that would be necessary to absolutely prove the safety has been done. It would not be ethical to, say, take a bunch of pregnant women and lather half of them with tons of makeup and the leave the other half untouched to compare the rate of birth defects.

Yes: Moderate use of topical make up is safe in pregnancy.
