PMD Personal Microderm Classic At-Home Microdermabrasion Machine ($159)
Instead of splurging on an expensive microdermabrasion treatment at the spa, consider treating yourself in the comfort of your own home with this handy tool. It's been a longtime beauty industry favorite, reviewed by a former editor years back. In her comprehensive PMD Personal Microderm Classic At-Home Microdermabrasion Machine review, she explained how it works, writing: "The handheld device has a plastic head that you press firmly against your skin. At the very top of the head, there's a small spinning disc coated with aluminum oxide crystals, which buffs away your top layer of dead skin."
