"i have had severe acne ever since i was about 14; when my period started. i have tried proactiv, every topical treatment and over the counter wash almost i know. i also have changed my diet and went on the candida cleanse as well as tried minocycline. but nothing, absolutely nothing has helped as it should have until i went on doxycycline and i am 18 now! it is the best thing i have ever tried! within a week, i noticed a huge improvement and it is week three now and all my cystic acne is gone and i am almost acne free expect a few hormonal pimples that i am about to go on birth control for. i am so thankful and i thank god everyday for letting me find it!! thank you, lord!"
