The science began with the creation of the Sonicare toothbrush. Now there is a product for your skin that will give you the ultimate clean. The Clarisonic brush head oscillates back and forth at a sonic frequency of more than 300 movements per second, clarifying and gently exfoliating the skin. Clarisonic is more than twice as effective as cleansing the skin manually. The flexing action between the outer and inner brushes works deep within the pores to loosen dirt and oil. With the Clarisonic System, cleanser, serum, and replacement brushes, your skin will have everything it needs to look its absolute best.
