"i&#039;m approaching 16 years of age and i&#039;ve been struggling with acne for 7 years. i&#039;ve tried so many products, with disappointing results. january of last year (2013) my dermatologist prescribed me birth control pills (tri-previfem) in combination with 100 mg daily doxycycline hyclate. i was on doxycycline for 8 months and then in august i stopped taking due to the health risks. in combination with the birth control, my skin transformed. it took a long time to get my skin in shape but it was well worth it. it&#039;s been several months since i&#039;ve been off of it, and my skin is better than ever. (i also continue to use differin and benzoyl peroxide treatment daily) highly recommend! (note: in my experience, the nausea subsides after a few weeks)."
