Sonic cleansing is not just for your face anymore. The Clarisonic Body Brush Extension Handle is designed to help you more comfortably cleanse the back, legs, knees and feet. The extension handle is for use with the Clarisonic Plus and Pro Systems with the Spot Therapy Body Brush Head on the body for noticeably softer, smoother, firmer skin. Helps reduce dry patches, skin appears healthier, and it cleanses so well that skin care products absorb better. The Body Brush Extension Handle is NOT compatible with the Clarisonic Mia, Mia 2, or Aria.
