An ultra-soft brush for those with delicate or extra-sensitive skin and for skin sensitivities like rosacea and acne-prone skin. All CLARISONIC® brush heads are made from a nonporous, soft elastomeric material, resistant to bacterial attachment. All brush heads are precision-designed to oscillate bi-directionally at a sonic frequency. For use with the CLARISONIC™ skin care brush. Made in USA. The Clarisonic Pedi Device is precision-engineered with an entirely new motor, running at a powerful "foot frequency" that safely exfoliates rough, dry foot skin. Our facial cleansing devices run at a gentler "face frequency," and aren't designed to drive the Pedi Smoothing Disc and Wet/Dry Buffing Brush Head. We cannot guarantee the efficacy, durability, or long term impact on the device itself, of brush heads not engineered by Clarisonic.
