acne
"I had fairly clear skin until I turned 25. My skin started freaking out and everyday I was waking up with a new cysts under my skin. Most of them gathered on my right cheek. I literally became a hermit for months and months because my self esteem was at an all time low. I could feel people staring at them during conversations. 

My dermatologist put me on two separate antibiotics and both seemed to actually make my skin worse. At my most recent visit, my dermatologist put me on Bactrim. We both talked about how I will have to get on accutane if this didn't work. 

After a week of taking Bactrim, my skin is completely clear (minus the scarring). I couldn't be more pleased. Finally feeling like myself again. :)"
