Star Travel Tips

"I take along Borba water, especially in handy travel packs. I Ziploc-bag all of my makeup. I pack Jane Iredale mineral powder, Shu Uemura's eyelash curler, Benefit's Benetint cheek stain, Vincent Longo Liquid Lipstick, Lipfusion Color Shine in Sweet, and Clinique Naturally Glossy mascara."

"I travel with a tube of Kiehl's amp#91;lip balm no. 1amp#93;."

"Magazines, towels, coolers, sunscreen, makeup, about 10 books, my iPod, definitely, and my Blackberry-which is not a good idea. You always think you're not going to get sand in it, but you always do."

"As soon as I check in I have to unpack. I have to hang everything up and put all my toiletries in the right places. It makes me feel settled. I love how organized and clean hotels are; there's just something so wonderful about perfectly rolled up towels and soaps in the right place."

"My clients keep coolers in their cars filled with low-fat yogurt, apples, raw almonds and bottled water," says L.A. nutritionist Valerie Waters. " Jennifer Garner, for example, likes to snack on low-fat yogurt with fresh berries when she's traveling."

Air travel can leave your face needing more than moisturizer. The fix? "Clinique CX Rapid Recovery cream applied 10 minutes before makeup," says New York City makeup artist Genevieve Herr, who adds that Kate Winslet turned her on to the cream ($75/1.7 oz.; clinique.com). "You'll be radiant."

"Pack a lot of white-sweaters, Ts, linen pants. They'll work with anything!"

"I travel with Lysol and spray it all over the bathroom."

"Three bikinis, a tankini top, a silk caftan, a cotton tunic, two tank tops, a ribbed cardigan, two pairs of white pants and a sun hat," she says. She also manages to sneak several "flimsy little evening dresses," one pair of high-heeled mules and some flip-flops into a single Louis Vuitton suitcase.
