Doxycycline
"I've had acne for two years (currently in year 9) and have tried all creams, but the creams never used to work for me since it wasn't my skin that caused the pimples, apparently there was just too much hormone production, so the Dr. prescribed me with 50mg of Doxycycline about two and a half weeks ago. The first week there weren't any signs of success, the second week it just seemed to get worse, (which everyone says is the side affect of this drug) but i haven't experienced the third week of being on this drug so i just hope my pimples clear up."
