Stars like Salma Hayek and Kate Bosworth turn back the clock with Le Soin Sisleya Anti-Age, the signature facial at the posh Sense, A Rosewood Spa. Tucked inside The Carlyle (where Tom Cruise often stays!) on New York's Upper East Side, celebs relax as the facial tackles fine lines and wrinkles, leaving skin more elastic. And the icing on top of the two-hour, $400 treatment? The included hand-and-foot treatment to help relive tension.
