"i got this about half through my sophomore year because everything i used never got rid of my acne. i just asked my doctor and she prescribed me whatever she thought was best. took about 2 weeks to start working, then boom my acne was gone. i occasionally got black heads but nothing like before. i was so happy. i started getting rid of most of my acne scars with fade cream since i had no acne anymore. but as of a few months ago (over a year of using it) it stopped working. i use it as i usually would, but acne is coming back. i guess my skin is now immune to it/built a tolerance, so it kind of sucks. now i have to go back and get a difference topical gel, but hey this was a miracle while it lasted."
