I'm always skeptical of these devices but a knowledgeable friend recommended it. I've used it for three weeks now, 17 minutes per day as instructed, and my skin is unquestionably improved. It is firmer, my age spots are faded and most surprising of all, my little jowls have disappeared and my neck is tighter. This particular machine, cleared for wrinkle use by the FDA, claims to have optimum results after 10 weeks.
I'm so happy with it after just three weeks, that I'll probably look 18 again soon. LOL. It's expensive but convenient for the home and the large size covers the whole face in one daily session. Love it.
