The Sonic Skin Cleansing System uses a patented sonic frequency of more than 300 movement per second to clean, soften and smooth skin.In just 60 seconds, the brush gently, yet thoroughly removes 6X more makeup and 2X more dirt and oil than manual cleansing alone. Removing these impurities has been shown to allow a 61% better absorption of Vitamin C, and better prepares skin for other products.
