"i&#039;ve been using this gel for probably about 2 or 3 years now. i started getting acne in around 6th grade where as i didn&#039;t start my period until 9th grade. i&#039;ve never had severe acne, there&#039;s just always been at least a couple zits on my face for as long as i can remember. i had no significant peeling or dryness when i started using differin, and i also had no immediate results. slowly over time, however, my acne is becoming less severe and less often. maybe it&#039;s because of the differin, maybe it&#039;s because i&#039;m growing out of it. i did stop using it last summer as a test and my skin got worse and worse for the entire month i stopped using it and it took a solid 3-4 months after i started using it again for my skin to return back to normal."
