Forget Brad Pitt. Jennifer Aniston is like a real-life Benjamin Button, looking more gorgeous and youthful with every year.

And the Wanderlust star, 43, finally revealed the secret behind her ageless complexion while promoting her new flick.

"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."

"I hope you saved the face afterwards" O'Brien joked. "That is eBay gold!"
