Clarisonic Alpha Fit Men's is designed specifically to clean dirt and debris off men's thicker and oilier skin. This sonic cleansing technology works at a frequency that allows three hundred movements per second, which allows cleaning six times superior than hand cleansing. The flexing action helps loosen any dirt or oil, and remove impurities from the pores. This results in smoother skin that allows for a closer, smoother shave. Men's daily brush was also designed to cater to men's needs specifically, with shorter bristles for resilient skin. This brushhead and brush combination creates the perfect formula for cleaning away sweat, dirt, and oil. Has a rechargeable battery that comes with a USB enabled charging cradle, and includes an LED battery life indicator.
