"i am a 23 year old female and have suffered from mild/moderate acne since the age of 12 my main problem area is my chin. i have tried every path to clear this including diet/skin care(several different brands)/water/exercise to clear my skin but the only thing that ever works and i find myself going back to is doxycycline. i have taken it on and off for over 10 years. i wish i could find a more natural path to clear my skin but doxy is so effective for me and it works within days. i have zero side effects."
