My acne was at its worse BEFORE birth control. It took til around February or so for the birth control to start working. I was then left (and still have) with many red markings from the huge breakout I got in my 1st semester of college.
My doctor said if I still wasn't satisfied with my skin when I came home from college in May, that I could go on Accutane. So I am now about 1.5 months into Tane to try and get my face superclear. For good.
