"i took doxycycline for one month exactly and it honestly did my face wonders! my doctor had it combined with 3%/5% benzamycin top gel, but i managed to finish the gel in 2 weeks or less because my break outs were bad and that would make them go away by the next day. now the doxycycline has helped a lot with the break outs not appearing on my face. i&#039;m 20 years old and got the pills prescribed to be taken once a day every day for a month and now i haven&#039;t broken out since i started. i&#039;m a girl and whenever i got my period, i would break out pretty badly, but this medication has helped a lot with that. i will ask for a refill on both medications. highly recommend to give them both a try."
