This product is wonderful! I have been using it for YEARS!!! It truly cleans your skin, deep down into your skin. Afterwards, your face will feel fresh, soft, and clean. I once had a serious acne problem....and this product helped get that deep down clean I needed to get rid of the acne which was caused by oils. The best part of this product...Completely affordable....OK, Now I'm starting to sound like a commercial. So in closing, just give it a try and see what a diffence it can make for you.
