Yah, I was the same way...never had anything major but wasn't even worth dealing with it. I first was prescribed Accutane by a doc in 8th grade and was on it for maybe 5-6 months. I had success while on it but I kept hearing these stories from guys with great complexion that swore they never got a pimple again after taking a full dosage of Accutane.
That wasn't the case for me. A couple years ago I order Accutane from overseas and self-medicated for about 8 months. I had the best results in this format. Since, then I never break out, even when on gear. You have to be very careful with the dosage protocol for Accutane according to your body weight. But the best thing I can advise you to do is not quit short.
You can actually waste the entire time you spent on Accutane by cutting it short. If you go too long though, it can actually have the opposite effect on you by making acne worse(same with taking too much). Do the research for yourself and try to stay on as long as you safely can and you won't ever have problems again. The chapped lips and dry skin will minimize as your body adapts. Accutane is a miracle drug for many.
