What is your most high tech tool

Navigating the world of skin care devices is tough. You can't exactly take skin care tools for a test run at Sephora the way you would a lipstick. And then, of course, there's the cost to factor in. (Do you really need to drop $300 on a wand to supercharge your face serums? Eh, probably not.) But every so often a shiny new piece of technology shows up that does for skin care what the first iPod did for MP3s—it changes the game.

Obviously, the stakes are higher when it comes to your face (nobody ever broke out from dropping $50 on a Zune), so over the course of the past year, we rounded up every innovative, raved-about skin care tool we could find and asked Glamour staffers and a handful of skin care professionals to answer the ultimate question: Is this thing worth it? For the devices below, the answer was a resounding yes. From cheekbone-defining face rollers to acne lights to a treatment device that literally delivers the benefits of a face mask in 90 seconds, read on for the skin care tools that'll truly change your complexion, including four Glamour Beauty Award winners.
