"i was hesitant to take this because of the mixed reviews, but gave it a try for my horrible acne and within a day noticed it started working. i didn&#039;t have any side effects and my face started to purge (giant pimples forming) and my skin was getting worse, so i knew it was pushing everything out of my face to start clearing my skin. a week later i woke up extremely itchy on my neck, scalp, chest, back, shoulders, feet, hands, basically every where and i had broken out in hives. i took a benadryl. then at midnight it happened again but worse. my neck was swelling up and the hives were the color of a tomato and i was insanely itchy. if i didn&#039;t take a ton of benadryl i would&#039;ve had to go to the er. happened today again. no longer taking them."
