Mia1 is the gentle, one speed cleansing brush for basic sonic cleansing. Clarisonic uses two mechanisms to give clean, radiant skin: oscillation technology and fluid forces. Oscillation technology means 300 micro massage movements happen every second to work within skin’s natural elasticity to sweep away dirt, oil and makeup. Fluid forces means Clarisonic takes the water on your cleansing device and uses it to flush pores clean. After only 60 seconds these patented technologies leave skin cleansed 6x better than hands alone and ready for treatment products or smooth makeup application.
