Travelling wreaks havoc on even the most well-looked-after skin, but with so many products out there claiming to bring jet-lagged skin back from the brink, how do you know which ones work? Our team of intrepid long-haul travellers have been testing out all manner of in-flight beauty buys, from makeup wipes to super serums, to find out which ones are truly worth investing in. Whether you're looking for something to help you doze off, a midflight hydrator to sooth tired skin, a quick fix to perk you up the morning after, or even a solution to a problem you never even knew existed (hint: in-flight sunburn!) we've personally selected our favourites from a whole host of travel beauty buys. And don't worry if you're travelling light, all these products come in travel sizes that'll fit in your hand luggage, though some are probably best saved for after you land (depending on how the man in 33A feels about sheet masks).
