Doxycycline
"I really like doxycycline. I have had mild acne since I was 11, however once I turned 19 I began having more frequent outbreaks on my face and severe outbreaks on my neck and chest. At first when I began taking this medicine it literally made me feel like my skin was on fire and caused excessive feeling. I then realized that the cleanser (clean and clear) that I was using along with doxycycline was causing this to happen. This makes your skin EXTREMELY sensitive, so be careful not to use anything too harsh on your skin or anything that will dry it out too much. Other than that, I love it! I have mild stomach discomfort, but it doesn't bother me too much. I was on it for six months and my face had cleared entirely and my back almost entirely!"
