Acne
"Follow the instructions and heed the words of the people who have used it before, and I feel like there&#039;s no reason Differin won&#039;t work for you. I&#039;ve had problems with adult/hormonal acne for awhile now, and this is the first and only thing that has made a seriously noticeable improvement. My skin did do the &quot;purge&quot; before it got better, but I just gave it some time like the instructions and other users said, and in about 3-4 weeks I noticed serious improvements in my skin. It looks MUCH better than it has in years. If you&#039;re not a patient person and will give up when the purge happens, then don&#039;t waste your money."
