Im 22 years old and when I was 20 I had a terrible cystic acne flare up. I ended up going on doxycycline which did a tremendous job of clearing my skin for about 9 months (I was on it for about 3) in August-October I small flare up which I don't believe was cystic because I cleared it with an OTC topical. Now I'm left with these terrible marks and feel very insecure.  I really need clarification that this is not permanent and that there's something I can do to help fade these. I don't know what to do...SOS
