No, they're not prohibited. See faa.gov, which lists them in the "Allowed" column under "Toiletry and medicinal items" for both checked-in and carry-on luggage.
However, if you bring them in your carry-on luggage, you need to ensure that they're under 3.4 oz (unlikely to be a problem) and placed in a transparent bag. In theory, anyway; in practice this doesn't really appear to be enforced for makeup, but why risk it?
