Jenna Dewan's Must Haves: From a $6 Cream to a Luxury Mattress

Dewan's travel must have is a new discovery that she used on her flight to New York City. It's the Drowsy Silk Sleep Mask ($79), and now, she can't imagine going anywhere without it. "It's thick and wraps around your head," she says. "You look a little bit like a pretty bug, but it works so good. This is a game changer."

Pro tip: If you have trouble sleeping on a long flight, a sleep mask like this can help block out light, allowing you to hit REM more easily. Dewan's hack for peak relaxation vibes: "Put your headphones in and you're just zoned out." Ear plugs are also great for this if it's particularly noisy. The Drowsy mask is made from silk, which is gentler on your skin and hair, reducing frizz and any uncomfortable tugging.
