My dermatologist prescribed me Differin Gel 0.3% about a year ago and I have been using it ever since with great results. My only question is, my prescription expired August 25th of this year and I am just a few days away from the end of my last tube. What will happen if I stop using it and substitute it with just cleansing my skin with Cetaphil and Aloe Vera?

Also, if I want to keep using it can I just go to my pharmacy and pick it up or will they deny my request since my prescription expired? I can't wait to schedule and appointment because then I'll miss some days without using it.

Thanks!
