"i&#039;m 15 and had pretty bad acne for about three years. my dermatologist percribed 150mg doxycycline haplate to take once in the am, also paired with 0.1% adapalene gel 2 or 3 times a week and cetaphil gentle face clenser every night this has tremendously helped my acne!!!! also i use panoxyl face wash (recommend by dermatologist) and a moisturizer every morning, you can buy it at walmart or walgreens. as for the doxycycline i haven&#039;t had any side effects other than little stomach aches but that&#039;s it. (i&#039;ve only been using this routine for 14 days so i don&#039;t know about what will happen but as for now it&#039;s pretty great :)"
