My son has tried every product on the shelves and also a number of prescription drugs and creams. Nothing helped. I bought him AcneFree Severe Acne Treatment and his face has cleared up within a week. I'm amazed! I've spent hundreds of dollars at dermatoligists that couldn't help! I highly recommend this product. My daughers, who don't have severe acne, love the regular AcneFree Treatment system. They don't need the severe product.
