acne
"acne has been a problem for me since 8th grade & I started using Differin my first day of senior year (major mistake due to it making your skin "purge" the first couple of days//weeks" by the end of October my skin was mostly clear & by the beginning of December my face was completely clear except for the occasional pimple every once in a blue moon. At the beginning it would make my skin burn especially during sports. It's sensitive to sun to defenitely use sunscreen when you're out. All around miracle medicine."
