www.acne.org Follow it just like it says. I am 32 years old and have had acne since I was 12. I have actually been asked to not return to the dermatologists office once because he could not clear it and didn't want to waste anymore of my money. Now I work with one and so far, this site has been the only thing that has given me noticable changes. It is not selling anything just getting the informatiohn out to those of us who need it. I have seen more improvement in 1 month than I have in the past 10 years. The 2.5 percent benzoylperoxide is VERY important too. Good luck!!!!!!!
