Skincare on a plane: why flying dries your skin and what helps

The best skincare on a plane is short. Start the flight moisturized, top up the spots that feel tight, keep your lips in balm, and wear sunscreen if you’re by a window in daylight. Everything else is optional. The air is what you’re up against: the CDC says cabin humidity is usually 10 to 20%, low enough to dry out your eyes and the inside of your nose, and your face is right there with them.

Why does flying dry out your skin?

Cabins are pressurized to the equivalent of about 6,000 to 8,000 feet (1,830 to 2,440 m), and the air that fills them is very dry. One small study put numbers on what that does to skin. Researchers measured eight women aged 29 to 39 on long-distance flights, with no skincare for 12 hours before or during the flight. Cabin humidity dropped below 10% within 2 hours of takeoff and stayed there. Skin hydration fell quickly on both the face and the forearms, and most on the cheeks, by up to 37%.

Eight people is a tiny study, but it puts a number on the tight-cheeks feeling a lot of us know from long flights, and it’s why the routine below leans so hard on moisturizer.

Should you wear sunscreen on a plane?

On a daytime flight in a window seat, yes. The Skin Cancer Foundation says UVA rays can pass through airplane windows, and the AAD’s travel advice counts planes and cars among the places UV reaches you through glass. Put on a broad-spectrum SPF 30 or higher before you board, and pull the shade down when the sun’s on your side. Flying at night? No sun, no sunscreen.

The best measurements come from cockpits, not cabins. In 2015, researchers writing in JAMA Dermatology measured UV in a small turboprop and found its acrylic windshield blocked UVB but let UVA through: 56.6 minutes at 30,000 feet gave the pilot the same UVA dose as a 20-minute tanning bed session. Pilots sit behind a big windshield facing the sky, so don’t read that as your risk in seat 32A. It does show that UVA at altitude is real and that glass doesn’t stop all of it.

Sheet masks on a plane: worth it?

Airplane skincare videos love a sheet mask at cruising altitude. It won’t hurt, but think about where the water goes: a sheet mask is mostly water, and in air below 10% humidity that water leaves fast. If you mask, follow it straight away with a cream, or the hydration leaves with it. A cream plus petroleum jelly on the dry spots does the same job in less space, and you skip the face reveal for the person in the next seat.

Is it bad to do skincare on a plane? Not at all, as long as it stays simple: clean hands, products you already know, and the strong stuff left at home. We’d save retinoids, exfoliating acids and peel pads for the ground, since a long flight is enough for your skin to deal with without adding a sting.

Safety note: If your skin cracks, itches or stings for more than a few days after you land, or a new rash appears, see a dermatologist and tell them about the trip.
