Or other similar treatments or are they a waste of time? Furthermore are there any potential adverse side effects?
As far as I can tell, a CACI facial will not do anymore than moving your facial muscles around as part of daily life. The microcurrent is supposed to be like a "workout" for your facial muscles. Unless you have some type of facial palsy, regular day to day activities of chewing, blinking and talking should suffice. The microcurrent not tighten up collagen or elastin fibrils which are in the skin. I don't think there is anything harmful about a CACI facial, I just don't think you will get any visible results from it.
