I just bought this ultrasonic face scrubber and I am learning how to use it. It comes with instructions but I found YouTube videos extremely helpful to explain how to use each function. This face scrubber came with 2 silicon caps, which are exactly the same, just different colors so you can share your face scrubber with someone else! They each have small bristles on one side and the wavy pattern on the other side to use for cleaning or moisturizing. It has a thin sleek design that is easy to hold while cleansing your face. It also has a long battery life after you charge it!
