I had terrible acne! I tried everything. Proactive, murad, and clinique! nothing worked. I actually started using this through my dermatologist. It was so expensive so I searched for it on amazon, lucky for me, it popped right up! I love it. i use it in the mining and at night with my clarisonic (you can also use the olay pro-x $29.00) brushes help to ensure you get all dirt and makeup out of your skin. this is the main culprit of acne!
