Doxycycline
"I have had acne since puberty; I'm 26. The first time I was ever happy about wrecking a motorcycle. I had to take Doxycycline Hyclate to clear up the infection on my knee due to the motorcycle wreck. I didn't even realize it but after 7 days my acne on my back was gone. I woke up in complete disbelief. I never really looked in a mirror because of my acne and now I look in the mirror every day. No acne. I cannot believe it. Going to a dermatologist in the next few days to receive an actual note to take more of it. "
