I have this brush applied now twice. The first time I had after bruising and a few "drivers" in the face, in short, it has been seen in retrospect, where and with whom I intensity of the brush in the face - so I would recommend that in advance to watch a tutorial on youtube, where shows you how to use the brush properly. My mistake was probably, have used that I classify the stronger and too long to make'm lingers. the second time around and after the tutorial everything worked wonderfully, which is silky soft skin, I am convinced that it skin quality after repeated treatment improves
