Read on for all 18 travel beauty tips.

1. Moisturize

Apply intense moisturizer the night before you are going to fly. This will help increase hydration in your skin before you're exposed to the dehydrating effects of cabin pressure, says Risi-Leanne Baranza, editor in chief of Palacinka.com, a beauty and spa industry publication.

2. Forgo the Foundation

Skip foundation on the day of your trip, and instead wear only moisturizer. Before you land, add a tinted moisturizer for a fresh, healthy look, says Baranza. If you just can't leave the house without some foundation, celebrity makeup artist A.J. Crimson says be sure to put on a primer first -- a silicone-based liquid or cream that puts a layer of protection between skin and makeup. It will help foundation and blush last longer and help keep your skin from becoming dehydrated.

3. Mist With Mineral Water

To refresh makeup while traveling, never glob on more foundation or blush. Instead, use a mister of mineral water and add a dab of moisturizer, says Los Angeles makeup artist Beth Binder.

4. Blot Out Oily Skin

To keep oily skin from getting out of control while traveling, bring blotting papers or rice papers and dab the "T" zone as often as necessary, says Crimson. "You'll dab up the shine and excess oil without stripping out the moisture, so you'll arrive looking fresher," he says.

5. Add Some Shimmer

Does traveling leave you feeling a bit green in the gills? Perk up a tired or sallow complexion with a soft shimmer powder or cream, says Joyce Carboni, founder and director of Skinsational Skin and Body Spa in San Diego. Stroke it lightly on the tops of cheeks, bridge of the nose, and lips for an instant pick-me-up no matter how tired (or queasy) you feel. Or use a combination of cream blush and lip balm to add color and moisture without dehydrating skin.
