Korean Women Share Their Extensive In-Flight Beauty Routines

Taking a flight messes with a lot more than your sleep pattern and nerves—it's a total skin predator. In fact, you're prone to losing one and a half liters of water on just a three-hour flight due to the relative humidity of the plane cabin, which can plummet as low as 10% to 15% (for reference, the average room in a home is 30% humidity). Think about a water bottle, for example. If you sip some of it on a plane and then descend to a lower altitude, you've probably noticed that the bottle has crumpled up. The same thing is essentially happening to your skin, which is frightening, to say the least.

The logical thing to do internally is to drink the water you're losing—the Aerospace Medical Association suggests taking in eight ounces of water for every hour that you're airborne. However, your skin could really use some external love, especially since there's a lack of research supporting whether or not drinking water actually hydrates the largest organ in your body. We know this because of science but also from scrolling through Instagram and seeing our favorite Korean beauty experts sharing photos of themselves sheet-masking in-flight (so often, in fact, we're surprised #planesheetmask isn't a thing). It's as if they've gotten in-flight hydration down to a regimented schedule, and given the fact these women continue to glow when they touch down in whichever city they land, we needed to know their carry-on essentials.
