Hopefully you're still lurking, but anyway I'll mention about accutane anyway.
I don't know too much about it because I've never taken it myself, but my boyfriend has and his cousin is taking it now.
Accutane is basically a last-resort for acne. It's quite effective, but the downside is that there are a lot of side-effects. They prescribe it to you for the most minimal time possible. You can look up the side-effects, but I think accutane is effective if you're willing to try it. I've also seen amazing results on Reddit if you want to search.
There are LOTS of bad side-effects. Depression, cancer, headache, irritation etc, Perhaps ask your doctor about it.
My boyfriend was very lucky and didn't experience any of the side-effects (well, not much anyway) and his cousin seems to be doing fine. Go over in detail with your doctor if you choose to.
