Hey I wouldn't worry too much. Accutane (my first course) cleared me 100%... yes, 100% for an entire year. I looked like one of those people we all envy with the perfect, flawless complexion, I almost forgot what having a zit was even like!! After about a year things started coming back, but VERY mild.. I had mild acne then for about the next two years, maybe getting a couple zits here and there once every two weeks or so.
Well now it is four years later and my acne has started getting a bit worse, I am hopefully going to start my second course of Accutane this Wednesday, and I am excited. You should be too! Accutane is the greatest. My boyfriend went on it like 7 years ago and he still to this day has PERFECT skin. For a lot of people, it clears them permanently. Be happy, you may very well be one of those people that after Accutane, never has to worry about zits EVER again!!!!
