Here are eight teensy treatments we recommend every frequent flier stash in her valise, from fledgling brand This Works (developed by the former beauty director of British Vogue). We love the One For All aromatherapy roll-on, whose lavender-and-coconut blend is gently antiseptic, and the Quick Spritz, with extracts of palmarosa oil and rosewood to soothe altitude-wrecked skin. And since each item weighs less than a quarter-ounce, you can throw them into the requisite plastic Baggie and sail through security. $59, www.barneys.com.
