Your poor skin needs moisture, too. That's where The Ordinary Hyaluronic Acid 2% + B5, $6.80, comes in. Massage it in before the flight, but keep it in your bag for the occasional reapplication throughout the flight.
Did you know you can be exposed to UV rays while you fly? It's true, that's why you need a moisturizer (have we drummed that into you yet?) with sunscreen. Check out a multi-tasking SPF moisturizer such as Drunk Elephant Umbra Sheer Physical Daily Defense SPF 30, $34, to defend against those nasty free radicals and keep your skin hydrated.
Dark circles become a real problem on flights, so banish them with a soothing eye treatment, such as the L'Oreal Paris Age Perfect Hydra Nutrition Manuka Honey Eye Gel, $24.99. This gentle formula has 2 key ingredients: caffeine to tighten the blood vessels and hyaluronic acid to suck all the moisture in. That combined with the cooling rollerball will wake up your undereye area, leaving you looking refreshed and rested.
Even if you properly hydrate before flying, your skin will likely appreciate a mid-flight pick-me-up. This Burt's Bees Hydrating Facial Mist, $12.99, is just what the doctor ordered. Give your face a spritz every couple of hours.
It's important to keep your lips hydrated; cracked, chapped lips look terrible and feel worse. Luckily, it's Mario Badescu Lip Balm, $8, to the rescue, for long-lasting lip hydration (and bonus, it doubles as a gloss).
