I've done it and have been very happy with the results. I probably needed to go to four or five sessions for my entire face. We worked on my nose first, then chin, jawline, forehead, and finally cheeks. The nose area was probably the most sensitive, followed by the cheeks.
What's great is that it's completely an outpatient procedure. I usually tried to schedule my sessions for Fridays, as there would be extra redness for a few days and occasionally puffiness. I haven't had any work done for five years, and I probably only now need to go back and do it again.
Metrogel never did anything for me, although my mother seems to think it helped her. The funny thing is that now that she's in her 80s, all of her redness has disappeared, even without laser treatments, and her skin color looks like she's back to the peaches & cream complexion of her youth. I guess that's one thing to look forward to!
