"i had very mild acne from 15 up to 17. my acne then became moderate. i tried the acne line exposed. with very little success. once i discontinued the use of the exposed skin care line. my acne became moderate to severe. at the time i was moving out, traveling to a new state, and finding a job/college. needless to say it was a very stressful time. from there i went on keflex. cleared half  my back and slightly improved my face over the course of 3 months. eventually i went on doxycycline with tretinin cream 0.5 percent. also proactive plus in the mornings. it has almost been a month and i am almost acne free.  i did not have a bad outbreak. no side effects whatsoever. i can take on a empty stomach. although i recommend eating and drinking."
