"i have had cystic acne since 13 years of age and now i am 22. for so many years since 18 i tried at home remedies, washing my face so often and eating well but nothing ever worked. having 2-3 cysts popping up every second day i just couldn&#039;t understand what was going on. i visited a cosmetic physician who then advised me on so many creams with me spending hundreds and finally she referred me onto a dermatologist who prescribed me doxycycline and epiduo- if only she did so much earlier i would have suffered 2 years less. those medication have rid of all active and no new ones have appeared from day one of use. my skin is dry but i&#039;d rather that than cysts all over and moisturizing isn&#039;t a bad habit to get into. thank you for doxycycline!"
