How to Care for Your Lips When Flying and in Dry Climates

Short answer: Aeroplane cabins and dry climates have very low humidity, which pulls moisture out of your lips faster than they can replace it, so they chap and flake. The fix is to prep before you go (exfoliate gently, then condition), keep an occlusive balm on through the flight and reapply often, drink water, and avoid licking your lips. In dry destinations, keep balm on you all day and reapply after sun, wind and swimming.

Why do my lips get so dry when I fly?

Cabin humidity is famously low — often far drier than a normal room — because the air at altitude holds very little moisture. In that environment, water evaporates from the thin skin of your lips faster than usual, and because lips have no oil glands to seal that moisture in, they dry out and crack quickly.

Dry climates do the same thing on the ground. Desert, high-altitude and air-conditioned or heated indoor environments all have low humidity, so lips lose water to the air constantly. The principle for both is identical: reduce the water leaving your lips and keep topping up a protective layer.

How should I prep my lips before a flight?

A little prep the night before and the morning of makes a real difference.

1. Exfoliate gently the day before. If lips are flaky, buff lightly with a fine scrub such as our Matcha Lip Scrub so balm can absorb evenly. Do this in advance, not on already-sore lips, and never on cracked skin.
2. Condition well. Apply a generous layer of Lip Balm the night before and again before you leave, so lips start the journey supple rather than already dry.
3. Skip drying formulas for travel day. Long-wear mattes and stains are the most drying finishes, so save them for after you land if your lips are prone to chapping.

What should I do to care for my lips during the flight?

The in-flight goal is simple: keep a protective layer on and keep your own hydration up.

• Reapply balm often. Every hour or so, and any time your lips feel tight. An occlusive balm slows the water loss that cabin air speeds up.
• Drink water. Cabin air is dehydrating overall, and well-hydrated skin holds moisture better. Go easy on alcohol and coffee, which are dehydrating.
• Do not lick your lips. Saliva evaporates almost instantly and takes lip moisture with it, leaving them drier than before — a fast route to chapping.
• Keep balm within reach. Put it in your pocket or seat pocket, not the overhead bin, so reapplying is effortless.

How do I keep my lips soft in a dry climate?

On the ground in low humidity, the same rules apply all day, plus sun and wind protection.

Situation	What to do
General dry air	Reapply balm through the day; do not wait until lips feel tight
Strong sun	Use a lip product with sun protection and reapply, and seek shade
Wind	Reapply after exposure; wind accelerates evaporation
Heated or air-conditioned rooms	Keep balm on; consider a room humidifier overnight
After swimming	Reapply once dry; water and salt or chlorine strip the surface

If you want everything in one place for a trip, a bundle such as the Lip Care Set keeps prep and protection together so you are not hunting for products on the road.

What should I pack for lips when travelling?

• A conditioning balm to reapply through flights and days out.
• A gentle scrub for the odd flaky patch, used sparingly and never on cracked lips.
• A comfortable tint or oil if you want colour — a Tinted Lip Oil gives sheer colour while conditioning, which suits dry environments better than a drying matte.
• Lip sun protection for bright or high-altitude destinations.

Aeroplane cabins and dry climates have very low humidity, which pulls moisture out of your lips faster than they can replace it, so they chap and flake.

Key takeaways

• Low cabin and climate humidity pulls moisture from lips faster than they replace it.
• Prep before you travel: gently exfoliate in advance, then condition well.
• Keep an occlusive balm on during flights and reapply roughly every hour.
• Drink water and do not lick your lips — saliva makes dryness worse.
• In dry climates, reapply through the day and after sun, wind and swimming.
• Choose conditioning tints over drying mattes when lips are prone to chapping.

Frequently asked questions

Why are aeroplane cabins so drying for lips?

Cabin air at altitude has very low humidity, so moisture evaporates from your lips quickly. Because lips have no oil glands to seal moisture in, they chap faster than the rest of your face.

How often should I reapply lip balm on a flight?

Roughly every hour, and any time your lips feel tight. Keeping a protective layer on continuously is what slows the moisture loss that cabin air causes.

Should I exfoliate my lips before flying?

Gently, and ideally the day before rather than on travel day. Buffing away flakes helps balm absorb evenly, but never exfoliate cracked or sore lips.

Does drinking water help keep lips from chapping when travelling?

It helps your overall hydration, which supports the skin, but it is not enough on its own. You still need a protective balm on the lips, because that is what physically slows moisture loss to dry air.

What lip products are best for a dry-climate holiday?

A conditioning balm for constant reapplication, lip sun protection for bright destinations, and a sheer tinted oil if you want colour. Save drying matte and long-wear formulas for when your lips are in good condition.

Why do my lips feel worse after I lick them on a plane?

Saliva evaporates very quickly, especially in dry cabin air, and takes lip moisture with it. That leaves lips drier than before, so licking sets off a cycle of worsening chapping.
