"I did this thing called like, a peel," she told Conan O'Brien on his talk show Wednesday night. "It's extremely intense - you don't realize you look like a battered burn victim for a week,' she said, referring to her obsession with what she called "laser porn." She added: "Then [the dead skin on your face] just kind of falls off - for eight days. It was horrifying."
