I have a mild acne problem and I've heard that three steps (cleanse, tone, moisturize) are a good way to treat acne. When I saw the commercials for Pure Zone, I decided to give it a try. I use the step 1 in a gel, twice daily. So far, my acne seems pretty under control. My only complaints would be that it's pricey when you have to buy all three steps at once and I wish the moisturizer had an SPF in it. Other than that, my acne is much better than if I did nothing at all. However, I don't recommend it for severe or stubborn acne.
