I've been using the acne.org regimen for 6 months now and I've seen really great improvements! I haven't had a pimple in a really long time! I'm really happy with the results but I still have some hyper pigmentation, i think that's what it's called, and some scarring as well. I've heard that AHA helps with that but I'm not sure if I want to use it if it won't really help with the scarring that is left from my acne. Is it supposed to help with scarring? Or just to help the appearance of your skin?
