"i&#039;m 37 and i suffer from pcos. i have been battening cystic acne since i was 25. i have spent thousands and thousands of dollars on meds, topical creams, different dermatologists and even laser treatments that have become costly. doxy is a quick fix and as long as you&#039;re on it, it will work. however, coming off the meds you&#039;re skin will start to purge so be prepared. i&#039;ve been mixing the right vitamins, cutting out dairy, eating gf, and keeping my diet rich in lots of green leafy veggies and high protein. i also have to exercise at least 3 times a week. taking probiotics is also extremely important. don&#039;t exfoliate too much and try to keep your cleansing regime simple. hope this helps."
