If you plan to stay up late during your trips, you're going to need your makeup to be in for the long haul, too. That's why you should spritz this Urban Decay All Day All Night Travel Duo ($19) on your face for all your vacation shenanigans. The primer gets your skin ready for makeup and gives you a boost of hydration via vitamin B3 and coconut water. After you apply your face, lock it in with the All-Nighter Setting Spray that lasts, well, all night.
