Hi,
I had to go on it a second..and a third...and as soon as it was out of my system (about two weeks afterwards) it came back. I have to say, it DID seem to improve it on my back...I no longer get many there at all...but because it's hormonally caused, accutane won't really help, it seems.
I've been hearing that spirolactone helps...but I was on it in my teens and it didn't work then. I'm hoping the metformin will help..dr said to wait about a month to see results =/
I wish I had more encouraging news for you..but for me, accutane just didn't do it. I used different dosages as well, and while I was on it, it worked like a charm....but then again, I had perfect skin while I was pregnant as well. It's all in the hormones, it would seem....
Good luck..I know how frustrating it is!
accutane..
