acne
"I've been using the 'Differin' Adapalene gel for around 3 years.  I used to have pretty severe acne when I was around 17/18. I started using the gel alongside Tetracyline anti biotic tablets and within a few months my skin had completely cleared up and marks had started to disappear. I'm now 22 and I haven't needed to use it for around 6 months."
