I've been dealing with moderately severe acne (which has progressively gotten better over the years) since I was twelve, I'm nineteen now and believe me I have a lot to say about it all, but I'll focus on this treatment. I was a 10% Panoxyl user for about 3 years up until two months ago when they started having production issues. It was a great product, I would highly recommended checking it out if you have moderately severe acne, but the reason it is inferior to Dan's treatment is mainly for just how drying it can be. My skin constantly cracked up and peeled, my skin could just never build a tolerance to it and I'm positive the irritation made things a bit worse, but it was still better than having pimples on every inch of my face. With Dan's treatment it comes with just 2.5%, that's a lot lower than something like Panoxyl's 10% so I always wrote it off, but reading some studies provided here and looking at Dan's regimen I decided to give it a shot. I think really though Dan's tactic of using more benzoyl peroxide to combat acne was the key. In conjunction with this light simplistic formula it makes that possible, which is ideal and damn does it work. Also, the fact that this treatment stays on your face as apposed to being lathered and washed off really guarantees your skin will absorb the benzoyl peroxide.
So overall try it out for a month, but look into how Dan uses it on this site. I can really see why a lot of people are having issues. And by the way, you have to stick with this stuff. Its benzoyl peroxide, its going to have the potential effect of initially making things worse and drying skin just as any other product but if you really want to rid yourself of your acne that's what it might take. Benzoyl peroxide is hands down one of the best treatments for acne according to studies and polls and I think this product utilizes it the best.
