I found this thread via a Google search for SA. I, too, have suffered some severe, cystic adult acne. My back used to be bad, but it has calmed down now.

Freepressright, you had mentioned using Dermacrine on your back and had some success. You had also recommended another resveratrol spray.

Which do think is better? I'm a fan of BPS, but was wondering if the other ingredients in there might have side effects. Obviously, there is that risk, but figured I'd ask.

Thanks. Great thread by the way. I think AndroFactory is coming out with something similar to SA.
