Acne
"acne has been a problem for me since 8th grade &amp; I started using Differin my first day of senior year (major mistake due to it making your skin &quot;purge&quot; the first couple of days//weeks&quot; by the end of October my skin was mostly clear &amp; 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&#039;s sensitive to sun to defenitely use sunscreen when you&#039;re out. All around miracle medicine."
