Overall, Lartey isn’t a fan of combining beauty products, particularly around the eyes. If you are going to use Aquaphor on your lashes, she recommends making sure they’re clean and dry. “The product is essentially a barrier, so you don’t want to trap bacteria under there. You can put Aquaphor on the lashes in the evening and mascara on in the morning,” says Lartey, who also likes clear mascara to give lashes a natural boost. Like Vaseline or castor oil, know that Aquaphor won’t grow your lashes, either. Rather, it can help moisturize dry and brittle hairs.
