Two Weeks Before
To rev circulation for an all-over glow, Mad Men star January Jones gets 80-minute full-body massages. As a spa veteran, she'd take full advantage of the Desert Sage Massage at Spa Mandalay, which incorporates a formula "with the purest essential oils inviting you to experience purification and rejuvenation."
The Palms Spa also offers a Ashiatsu massage, perfect for tough-as-nails stars like Angelina Jolie and Jessica Biel, in which therapists "expertly manipulate the muscles using their feet" while supporting themselves with bars suspended from the ceiling!
One Week Before
Stars start concentrating on their complexions seven days before they hit the red carpet. Sandra Bullock often opts for a brightening facial like the Vitamin C Radiance Facial -- which, at, helps reduce the signs of sun damage and aging -- at the Bellagio Spa & Salon while Anna Paquin goes with a clarifying skin treatment.
The ultimate red-carpet-ready facial, however, can be found at Canyon Ranch Spa Club. The 80-minute, Absolute Custom Facial is "customized to suit all skin types and is perfect for those looking for results now." The aesthetician assesses the A-list face to determine the best approach for radiant, firm, dewy skin.
One Day Before
Famous fingertips must get loved in advance of the big night, and everyone from Zoe Saldana to Diane Kruger can try on the season's hot colors -- gold, silver and bronze -- at the Reliquary at the Hard Rock Hotel & Casino. They even offer last-minute airbrush tanning, a technique loved by the likes of Olivia Wilde, Ashley Greene and Kim Kardashian.
The day of, get a blow-out at the Brannon Hair Salon, also in the Hard Rock Hotel & Casino. Celebs such as Nicky Hilton, Jon Bon Jovi and Britney Spears have gotten their locks cut and styled at the exclusive, four-chair salon.
One Day After
When the stars' big night is over, there's nothing they need more than a detoxifying spa treatment. The Lotus Flower Bath at Caesars Palace's Qua spa is a 20-minute, "concentrated lotus flower extract bath" that makes the perfect remedy for jet lag, hangovers, headaches or toxicity and soreness.
