Molly Sims's Must Haves: From a Portable Charger to a Béis Travel Case

While Sims has tested her fair share of beauty products over the years, few have blown her away like the TheraFace PRO Percussive Skin Care Device ($399). "This facial device is an all-in-one [tool] that will help reduce wrinkles, boost circulation in your skin, while also reducing facial tension. It's a must-have if you are wanting radiant, glowing skin," Sims says.

Pro Tip: This percussive tool can be used to relax facial muscles, as well as relieve any lingering tensions. It's available to shop in two bundles, including the TheraFace Pro package, which comes with a set of hot and cold rings, or a larger bundle that includes six separate facial treatments.
