I never understood all the buzz about the Clarisonic skin-cleansing system; after all, I’ve been washing my face with a washcloth all these years with success. Why would I need a machine to do it? Well, consider me humbled—and hooked. After just a few weeks, my face doesn’t feel clean without it. I’ve been using the new baby Clarisonic—Mia, which is the travel-size version of the original. The brush gently vibrates at a sonic frequency of more than 300 movements per second for a full minute, then shuts itself off, leaving your face really soft and really clean. How clean? Clinical results say the device removes six times more makeup and twice as much dirt or oil than manual cleaning. The device holds a charge for a month of twice-daily washes and can be used in the shower. Good things do come in small packages. Available in a rainbow of cute colors, $149 at Sephora or clarisonic.com.
