You're at arrivals. You are at the apex of a 13 hour flight to somewhere fabulous. A small polythene bag has been thrust into your hand. What do you put inside it? What is the one beauty mainstay that will get you from A to B as painlessly as possible?

I should really be exempt from this question since I fill my plastic bag until it's fit to burst with facial oil, lip balm, sleeping pills, hand lotion, face masks and, curiously, cream blusher. If I can't get it all in one, I make my boyfriend carry another for me for overspill. Because plane air is to skin what the Industrial Revolution was to lungs; it's nasty, it's filled with weird unknown things and it makes it shrivel up like a prune. But, as ever, beauty saves. 

Everyone does flights differently. In fact, admirably, many of the Never Underdressed team go minimal, eschewing the bag completely (now that's a nice feeling) but most of us have that one product (G&T notwithstanding) that makes it all better.
