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.)

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.
