“Many travelers overlook the need for sunscreen during flights, but UV radiation is actually stronger at higher altitudes,” confirms Dr Anjali Mahto, consultant dermatologist and founder of Self London. “The windows on airplanes do not provide adequate protection against UV rays,” she continues. In fact, UV levels increase by 10% for every 1,000m increase in altitude, according to the World Health Organization (WHO). “Without proper protection, prolonged exposure during air travel could potentially lead to sunburn, premature ageing and long-term skin damage.” This is especially true if you’re taking a daytime flight, and if the blinds are up throughout the duration. Combine this with the recirculated cabin air — which is often dehydrating — it’s no exaggeration to say that your skin goes through a lot every time you take to the skies.
