Yearly Air Travel and the Importance of Wearing Sunscreen During Flights

In the skies, where the atmosphere is thinner and offers less natural protection against harmful ultraviolet (UV) rays, wearing sunscreen on planes becomes critically important. At cruising altitudes of around 30,000 to 35,000 feet, the increased exposure to UV radiation can lead to premature aging, skin irritation, and an increased risk of skin cancer[1][3][4].

This heightened UV exposure occurs due to the significant thinning of the atmosphere, which means less natural protection against UV radiation. As a result, passengers are exposed to up to 60-80% more UV than on the ground, even though they are inside an airplane[1][3][4].

Airplane windows do not block all UVA and UVB rays, leaving skin vulnerable to damage that can accelerate premature aging, cause skin irritation, and increase the risk of skin cancer—a leading health concern highlighted by the EPA[1][5]. To combat this, applying broad-spectrum SPF 30 or higher before boarding and reapplying every few hours during long flights is a necessary protective measure[1].

In addition to applying sunscreen, other recommended in-flight skin protection strategies include keeping the window shade partially down during peak sunlight hours if seated by the window, wearing UV-protective clothing such as long sleeves or scarves, choosing mineral-based (physical) sunscreens for better UV blocking, and staying hydrated to counteract the dry cabin air which can further irritate the skin[1][2].

For convenience and continuous protection, carrying travel-sized sunscreen for reapplication during layovers or after landing helps protect against cumulative UV damage throughout the entire travel period[1].

### The Best Sunscreens for In-Flight Skin Protection

Ideal sunscreens for use on planes should be:

- Broad-spectrum SPF 30 or higher to block UVA and UVB rays effectively - Mineral-based (physical blockers) containing zinc oxide or titanium dioxide, which provide more reliable protection and are less likely to irritate sensitive skin - Hydrating or moisturizing formulas to counteract the dehydrating cabin environment - Non-comedogenic and lightweight to avoid clogging pores and feeling heavy during flights

Using these types of sunscreens along with protective clothing ensures optimal skin defense against the combined challenges of UV radiation and dry cabin air during air travel[1][2].

Some recommended sunscreens for in-flight use include La Roche-Posay's hydrating sunscreen, which protects without feeling heavy, BYOMA's affordable option that offers velvety smooth application with no greasiness, and Supergoop!'s lightweight formulation that sinks into the skin easily and without effort[6][7].

For those with oily skin, Dr Rishi Mandavia suggests that texture and formulation are important factors in finding the best sunscreen. He recommends sunscreens that are breathable, hydrating, and non-greasy for extended wear[8].

Dr Hall advises layering SPF over a hydrating serum (such as one containing hyaluronic acid or niacinamide) and using a facial mist mid-flight for additional hydration without disturbing sun protection[9]. Ultra Violette's SPF mist is recommended for easy top-ups during the flight, providing peak protection with regular sprays[10].

In conclusion, wearing SPF on planes is essential for frequent flyers, those who like to sit near the window, and those who do long-haul flights during the daytime. By following these tips and using the right sunscreen, you can ensure that your skin is protected against the increased UV exposure at high altitudes.
