I have this machine, you need to use it for 8 week 2 or 3 times a week and after that use it as mantenance mode a couple of times a month. I feel my skin is plumper when I use it. I have done the 8 week treatment with this machine on my mother and while it has give her a nicer complexion it has not do much for her lose skin on jawline and neither on her wrinkles
