Facial?$345 for a series of three If you want to get gorgeous for Oscar, you'll need to start at least three weeks ahead of curtain time, says Ole Henriksen, owner of the Ole Henriksen spa in Los Angeles, pictured here. Celebrities like Renée Zellweger and Ellen DeGeneres, he says, indulge in a regimen of $345 facials (some cleansing, o thers restorative) in the weeks leading up to the show. Perfect Hair?Up to $4,000 Best Actress nominees such as Penelope Cruz might turn to such top stylists as Sam Leonardi, whose services can cost anywhere from $2,000 to $4,000, depending on the celebrity and the complexity of the job. Basic styling obviously comes cheaper than an elaborate updo. Celebrity Stylist ?$7,000 Stylists select Oscar-worthy tuxedos for male nominees and dresses and accessories for females. Jennifer Rade, for example, has been styling Angelina Jolie for years, and she chose the slate gray strapless dress by St. John that Jolie wore to the 2007 Golden Globes. Glowing Skin?$400 to $600 for Triad medical facial, $400 for medicure pedicure Wear a million-dollar necklace or a $10,000 pair of shoes, and chances are that cameras will shoot close-ups of your neck and feet. Dermatologists like Dr. David Colbert at the New York Dermatology Group, pictured here, offer a medicure pedicure (laser resurfacing, exfoliating and hair removal for the feet) and a Triad medical facial for the neck (microdermabrasion, laser resurfacing and a glycolic peel) to smooth rough skin. Training Session at Peak Performance ?$110 per session, 6 times a week Trainer Lauren Goldberg of New York exercise studio Peak Performance recommends celebrities come in at least 3 to 6 months in advance if they want the body definition needed to wear short dresses, plunging back lines or skinny fitting tuxedos. Session With Celebrity Makeup Artist ?From $2,000, depending on the artist For nominated actors and actresses, studios enlist the services of such top makeup artists as Dior Beauty spokeswoman Pati Dubroff. She'll be doing Kate Winslet's makeup for this year's show.
