Cabin air on commercial flights typically has humidity levels below 20%, far drier than the 40%–70% range where skin feels most comfortable. This environment can quickly dehydrate the skin, weaken its barrier and limit the effectiveness of even the most careful in-flight skincare routine.
Skincare expert Annabelle from Fresha identifies three common mistakes that can undermine efforts to maintain healthy skin during air travel. Her advice focuses on hygiene and internal hydration, alongside topical products.
Bring your own pillow
Many airlines do not thoroughly wash in-flight blankets and pillows, meaning they may carry oils, bacteria and residue from previous passengers.
“Even if you have just completed a rigorous skincare routine, the impurities and bacteria on the provided pillows can lead to breakouts or irritation on very sensitive skin,” says Annabelle.
Friction is another concern. Aeroplane pillow fabrics are often rough, and movement during sleep can rub against the skin, disrupting applied products and causing irritation. The material can also absorb skincare products, reducing their effectiveness.
“I would always recommend travelling with your own pillow. This way you know that it is clean and has never touched someone else’s face. A silk pillowcase is an even better option as this creates a much more skin-friendly barrier, which will help keep your skin clean, reduce friction and allow your skincare to properly absorb into your skin whilst you rest.”
Silk pillowcases are widely noted for their low friction and reduced absorbency compared with cotton or synthetic fabrics, helping skincare products remain on the skin rather than soaking into the material.
Sanitise your entire seat area
Many passengers wipe down tray tables but overlook the rest of their seating area.
“It might look clean, but it can harbour bacteria and residue from previous passengers that will then be in very close contact with your skin,” Annabelle explains.
Touching unsanitised surfaces such as armrests, seat fabric or tray tables and then touching the face can transfer bacteria and undo skincare efforts, potentially leading to breakouts.
Studies have confirmed that high-touch surfaces such as tray tables, armrests and seat pockets can harbour significant levels of bacteria, including strains that persist for days. One analysis found tray tables carried more than eight times the bacteria per square inch compared with lavatory flush buttons.
Wiping down the entire seating area with sanitising wipes upon boarding helps reduce the transfer of microbes to the face.
Stay hydrated
“It is all good and well having a 5-step in-flight skincare routine, but hydrating from the inside out is the foundation of any good skincare regimen, and it is more important than ever on a flight,” says Annabelle.
The dry cabin environment strips moisture from the skin and weakens its natural barrier. Without adequate water intake, the body cannot maintain skin hydration, regardless of how many topical products are applied.
Research shows that cabin humidity can drop below 10% within two hours of takeoff and remain low throughout long-haul flights, leading to a measurable decrease in skin hydration. Internal dehydration worsens this effect, as the body prioritises vital organs over skin moisture.
Experts recommend drinking water before, during and after flights to support both overall well-being and skincare effectiveness.
Addressing these three areas can make in-flight skincare routines more effective. Bringing a personal pillow with a silk case, sanitising the entire seat area and maintaining steady water intake can help counteract the harsh cabin environment and leave travellers looking and feeling fresher on arrival.
