Doxycycline
"I had mild acne for almost 2 years and kept it at bay using over the counter treatments such as face washes and proactive (which didn't work at all). As I approached the 9th grade my doctor put me on doxycycline to prevent scarring. Even after the first week I saw immediate results! It was truly amazing after 6 weeks. I sometimes have bad stomach pain and peeling skin but it's really a small price to pay for good skin. Even though I still have mild breakouts and small larger pimples I have another month to go on my prescription. HIGHLY RECOMMEND, IT KEPT ME OFF ACCUTANE."
