Mine went away but comes back now only with my cycle (with the exception of one or two "permanent" ones--red or purple bumps that flare up occasionally).
I had 2 lots of accutane when i was 15/16. I was completely clear for about 4 months for the 1st time since I was 11 when I started getting acne. Then it came back again! Not as bad, but bad enough I'm 19 now and still battling!
