I remember being in Sephora right around the time the first Clarisonic—the vibrating face-cleaning brush that produces more than 300 movements per second—came out. The store didn’t even need a salesperson to talk it up: A group of women was gathered around the display, gleefully sharing stories about how amaaaazing it was. How it works: You squirt a bit of your cleanser on the bristles and brush it in circles across your face, removing dirt and oil while amping up circulation. Spas have started incorporating the gadget in facial treatments. And now there are more opportunities to include the brush in your daily regime: There are a half-dozen competitors on the market. I road-tested a few.
