My dermatologist had me use this exact product when I had cystic acne on my cheeks, ouch. She had me use a 5% benzoyle peroxide wash from Topix and then exfoliate with this every other day. Use a good moisturizer afterward and my skin miraculously began to clear up. I was so happy with this product. It did make my face very oily because it was harsh on my skin and slightly burned when I used it, but my skin was flawless. I don't find the need for this anymore since I grew out of my cystic acne. I don't know where I would've been in my teen years without this stuff.
