I've been using Epiduo for about 2 and a half months now, but I see absolutely no difference. I've used it every night except for 2 days when my face felt really irritated. My dermatologist is apparently out, so my next appointment is not for a month; I'm assuming my only option at the dermatologist is going to be accutane, but I want to stay away from that until I'm out of options. Now my question is, should I try out M2 Skin Refinish 20% or wait until my appointment?
