Been having these for a while now. At first, great results, then went onto once a month for maintenance. Not sure what would happen if I stop....is my face going to collapse in on itself and lose muscle tone? Or is there an optimum result, and I can have them less often. It's quite expensive, and I think if its not actually worth it, I'll reduce or stop it. Anybody any experience of it, or anything that can do great work miracles without spending as much. TIA
