Rumors have been swirling about Britney Spears‘s alledgedly puffier pout for the past few weeks, but if the popster had her lips plumped, she’d hardly be the first star to do it. Jessica Simpson had to wait four long months for her lip-job to de-swell — “It looked fake to me; I didn’t like that,” she admitted –Spears has an alternative to holding her hand in front of her mouth for the four to nine months fillers such as Restylane and Juverderm typically last: hyaluronidase, an injectable enzyme that reverses the puff within 24 hours. “It takes away the uh-oh factor,” says Calabasas cosmetic dermatologist Dr. Anna Guanche. “Get your lips, take them home, and if you don’t like them, bring them back.” One caveat: no refunds — and the fix runs about $200.
