"so i began using ziana in the beginning of december 2014. just as the others said, my skin did go through a purging process for about 2 months and a half. almost coming to the end of the third month, i began seeing some of my acne disappear from areas i had always broken out in. around march (4 month mark) my skin had drastically improved. however, the only side effect is my face is super oily even when i wash it in the morning, it starts to produce oil hours later. in my opinion, this is a small price to pay for clear skin. my advice to new users, stick with it no matter how awful it may seem! this medicine performed miracles for me"
