The Sonic Skin Scrubber uses a high-frequency pulse of 3,000 vibrations/minute to deeply clean the skin, gently exfoliate, clear blackheads, and remove excess oil and dirt from your face. Daily use can relax muscles, promote blood flow with micro-circulation, increase collagen production, shrink pores, and help you to solve many skin problems. Use your favorite creams and serums to maximize skin absorption.What's in the Box?
