acne
"I used Differin gel for almost 2 years on my face. I had moderate acne that no OTC medication helped and some prescription medications didn't help much either. Differin took about 2-3 weeks of daily use before I saw any change but about 2 months into the treatment my face was pretty much all clear with no pimples. It was amazing. My skin did get red and itchy during those first few weeks but my doctor said it was common and to keep using because my skin would get used to it. It did and it still keeps my skin the best it's ever looked. Also, it's now available over the counter at drug stores."
