This guy seems to have found the answer: Acne.org. If you go to his web site, click on "Get Clear" and follow his instructions (to the letter!) you will have clear skin. I used his process on both of my teen-agers, who both had different acne issues - but both were BAD - and we had amazing results in a short amount of time.
I liked that it was inexpensive - since I was treating 2 kids - with products you can buy at the local drugstore. He sells a product line that he developed and is very reasonable, but I went ahead and found equivalent "store brands" to use with his process.
My kids were pleased with the results, although it was quite a commitment for a 14 and 15 year-old. We are able to keep their acne under control by just occasionally getting militant with the products.
