This is a great product that will get you noticeable results. Your acne will start to clear up in only a couple of weeks. I think for being non prescription strength, that is incredibly fast. Effectiveness Once you apply this to your face you can really start to feel it getting to work. And in a couple weeks you can really start to see that some of your acne actually is clearing up. Ease of Application It's really easy to use this. Just apply it to your face and you can leave it only for only a couple of minutes and then you wash it off and you're all set and ready to go. Convenience It doesn't take more than a couple minutes for a treatment so you can do this in the morning before you go to work or school. Side Effects I haven't had any negative side effects from using this product. It is completely safe to use for everyone. Immediacy It gives you an immediate cleansing from oil on your face. To see actual acne going away I would give it a couple weeks.
