How long until you see a decrease in oil production while on spiro? Oh and since you guys are discussing birth control, I heard estrostep is the best one. And one more question: What kind of doctor should I go to get prescribed spiro? Derm, Gyno, Endo...? A few months ago, when I was at the derm, she told me she didn't want to give me spiro because she wanted to try doryx and retin-a micro. Well, I've been on doryx for four months and haven't seen any improvement, and my skin is still extremely oily. She promised the retin-a would make my skin less oily too, and I think it just made it more oily. So hopefully, when I go to the derm next week, she will prescribe spiro! :D
