My chin had been breaking out badly and I wanted something to try to speed up healing so I picked this up as it stated that it prevents and kills acne bacteria. I used it for about a week and found that it did make a slight improvement in the appearance but that could have also been because I haven't been bothering them. Which is bad I know. Another week into it I out it on and the next day I noticed that my chin had this weird raised rash. It felt rough and dried out. It didn't hurt or anything and immediately stopped using it. Maybe its the type of skin I have which is a combination...I don't know what had happened and have yet to use it again.
