Best skin tightening procedure for back?

First of all, none of the devices that are supposed to be skin tightening, actually tighten the skin. Renuvion works on tightening the connective tissue between the skin and the muscle and while it contracts the connective tissue, it effectively pulls the skin closer to the body, making it appear less.loose. Skintite creates energy between two poles of the device that’s introduced into the skin. The energy that is created creates heat, and there is a limit as to how far this temperature can go because burns could be created on the skin. The skin is not being really tightened, the temperature melts the subcutaneous fat. In the long run, the skin actually appears looser as the body gets rid of the dead fat. Bodytite cannot, and should not be repeated in my personal opinion, however, Renuvion can be repeated if necessary. I hope this helps and good luck from New York City Plastic Surgery .
