21 Beauty Products Our Editors Never Travel Without

"I have difficulty falling asleep anywhere, let alone sitting upright in the sky, but the Iluminage Skin Rejuvenating Eye Mask ($35) lulls me into deep sleep on turbulent flights. I pair it with a set of earplugs and a bit of lavender essential oil to get the snoozefest started. The cushy undereye padding makes my face feel cradled, ensuring that I'm out within minutes. The fact that the mask is woven with antiaging copper fibers is just a bonus!" — Emily Orofino, assistant editor, Beauty
