You'd think Ms. Hilton would maybe like fresh-cut cucumbers to lay over her tired-from-DJing-until-dawn eyes, but ew, do you even know where those vegetables have been? Instead, she sticks on undereye patches while "doing my make-up and putting on my lashes." (They're neat little half-moons infused with caffeine and collagen for de-puffing and smoothing.)
Another one for skincare first, the model packs cleansing wipes, "just because, when you are at the airport, it’s not fun to wash in the bathroom." Or do anything in an airport bathroom, come to think of it. Her favorite Maybelline towelettes have been discontinued, but these should do the trick.
Insert the tab and pull to tighten, because this one's a doozy. In a Goop post, she picked active silver (sprayed in her vicinity to "keep germs at bay") and magnesium drink powder as travel must-haves, because "they say magnesium calms the nervous system." To be fair, though, she did list a good face cream first.

Weird that your roots can still get greasy when the ends crisp up in that dry recycled air, eh? To guard against the aforementioned phenomenon, Perry brings a travel-size can of texturizing spray for a just-washed feeling. Best make sure it goes in your one Ziploc baggie, or else they'll rifle through your luggage, making everybody else in your party want to hurt you.
