6. Skip Long-Lasting Lipsticks
To give lips color that will last through your trip, skip the long-lasting lipsticks -- they'll only dehydrate and parch your mouth. Instead, Crimson says, color your lips with several coats of a lip stain, let dry, then top with a clear gloss. Reapply the gloss throughout the trip and your lips will look "just-made-up" fresh.
7. Apply Lip Treatment Liberally
You can further protect your kisser by packing a lip treatment in your carry-on bag and using it liberally while traveling, says Silverjet Airlines flight attendant Danielle Easton. Her one flying "must have": "A medicated lip balm, because it won't rub your lipstick off and it keeps lips hydrated while flying," she says. It also works on bus and train rides, she says, when high heat or air conditioning can also cause lips to feel dehydrated.
8. Chill Out Puffy Eyes
To reduce under-eye puffiness after a long trip, Pam Inman, American Hotel Lodging Association vice president and chief operating officer, says to put crushed ice in a washcloth and apply it under the eyes. "It's an automatic wake-up call that makes you look and feel immediately fresher."
9. Perk Up Your Peepers
Watching back-to-back in-flight movies, or reading that paperback novel cover to cover, can also cause you to arrive at your destination with red, watery, not-so-attractive eyes. To avoid it, Los Angeles image consultant Allison Dickson, founder of TheA-List.com, says don't forget to bring eyedrops. "They will lubricate and soothe eyes if you're reading or watching a movie, and refresh and wake up your eyes if you nap," she says.
10. Love Your Naked Lashes
Avoid wearing mascara while traveling, says the Travel Channel's Samantha Brown, star of the Passport To ... series. "If I take a little nap, I wake up and find the mascara has left a migratory trail down to my cheeks." She also suggests skipping cream eye shadows, which have a tendency to move around on your face as you snooze.
11. Banish Bright Nail Polish
Skip the brightly colored nail polish when traveling. It chips too easily and leaves you looking unfinished, says Carboni. She recommends buffing and polishing nails to a natural sheen for a clean, crisp look, or applying a neutral, sheer color that won't call attention if it does chip.
12. Keep Your Hands Off Your Face
To minimize breakouts while you're on vacation, dermatologist Erin Welch, MD, says to avoid touching your skin while you travel. "You can pick up any number of unknown bacteria that can result in any number of skin problems after you arrive," says Welch, a professor of dermatology at the University of Texas Southwestern Medical Center in Dallas. If you're going to apply makeup while you're in transit, Welch says use an antibacterial hand wash on your hands first to further protect your skin.
