I have had this before around my eyes 3 year ago and love the improvement with skin texture/tone and some tightening. I just had the area around my mouth done 4 days ago with a combination of Active/Deep FX and am doing well.
Yes the the doctor used numbing cream as well as a injections to manage any discomfort and it worked wonderfully. Most of the swelling is already gone, i'm pink and skin is slowly flaking/peeling off. It is my understanding that collagen growth continues for 6 months post procedure so you won't realize the full result until that time.
It sounds like THE most important part of this procedure is choosing the right doctor! Someone with lots of experience who knows what he/she is doing! Anyway, very happy before, already happy anticipating improvement over the next 6 months.
