"I have the same breakouts as everybody else," Scarlett has told Elle. So how does she keep blemishes at bay? "I never go to bed with makeup on, even if I come home at 4 a.m.," she says. "My skin's sensitive, so I have to use things without fragrance, like Cetaphil. And I clean my makeup brushes once a week. People don’t realize how dirty their sponges and stuff are! Bacteria — that's what makes you break out."
