acne
"I've dealt with moderate acne for ten years.  Last year, I started getting constant cystic acne on my back (one or two at all times) and some on my face. The ones on my back were really scarring.  I went on minocycline for three months and I have been off of it for about three months. The cystic acne completely disappeared and has not returned.  I still get the occasional pimple, but it is not cystic and MUCH less frequent than it was in the past.  I am very pleased that the medicine cleared up my skin and that I no longer need to take it.  Even if my acne returns in the future (I hope it doesn't), the past six months of clear skin is easily worth the time and money."
