Thanks to a unique "dual motor" design, this device doubles the vibration frequency while effectively adsorbing deep skin blemishes. It is also designed to minimize hand vibration and numbness. Compared with other facial cleansers on the market, it has more than 50% more fine contacts and is both cleaner and more efficient while reducing skin scraping. Many products cause lateral friction on the skin, whereas DOCO protects the cuticle from thinning.
