Laís Ribeiro's Must Haves: From a $9 Eye Mask to a Celebrity-Loved Cleanser

Ribeiro can forgo a pillow but can't go to sleep without her 3D Sleep Mask With Contoured Cups ($9, originally $20). Unlike other sleep masks on the market, this one has contoured cups made from memory foam that cushions your eye area. "When you put it on you, it's a blackout. You don't see anything; it really covers everything, so you don't see any light. So after I found that mask, I travel with that everywhere as well," she says. The mask also has an adjustable strap, so you can get a secure fit no matter how much you toss and turn. It comes in a variety of colors, like black, navy blue, purple, and gray.

Pro tip: To get into the mindset of rest and relaxation for bedtime, Ribeiro likes to spend some time in her sauna and take a calming night shower. "The stress release, the muscle relief, I sleep better because you're so tired as well from the heat," she says.
