Doxycycline
"I went on doxycycline for about 3 months (started at 150mg and slowly went down to 50 mg in the last month) and paired it with finacea topical cream at night. While my skin cleared up beautifully for those 3 months, my cystic acne came back even worse than before once I got off of the pills. Now I'm about to start accutane because my skin got so bad after it"
