"my acne started when in my 20&#039;s and i struggled with it for about 30 years with various levels of success and complications. i took a job managing a dermatology practice and one of the doctors put me on some topical stuff that just tore my face up. a visiting phamacutical rep kindly pushed a bag towards me one day and hinted that it might work a bunch better than what i was using. doxycycline has been a miracle for me... most days 50mg and occasionally during a flare, i&#039;ll take one each 12h. results (after 30 years of struggle) have been nearly ideal... can&#039;t recommend this treatment enough."
