I'm 31 and suffer from adult acne. The Clarisonic device was a life saver and the acne cleansing brush even more so. I have very sensitive skin along with acne, so I was elated to know that I could switch my original brush out for this one. The brush works really well, not too harsh on the skin especially during times of flare ups. I only use my brush once- in the night. Its most effective for me doing it this way, as I dont need to exfoliate twice daily. Using it in the night ensures that you get all the days worth of 'gunk' off your face .
I love this brush head! This is my first time replacing the brush since I bought my clarisonic so I had the one that it comes with. This one was a bit more abrasive which I wanted because it exfoliates a bit deeper but its not too much. Im giving this 4 stars just because it doesnt lather the soap the way the other one does so I prefer to cleanse first. Still love this brush head!
