Renuvion is a minimally invasive skin-tightening treatment primarily used on the stomach but it can also be used on the neck, back, thighs, breasts, arms and legs. Tiny hidden incisions are strategically made on the areas to be treated and then a J-Plasma device is used to sub-dermally deliver cold plasma to the area being treated. J-Plasma is created by energizing helium gas so its atoms and molecules ionize into negatively charged electrons and positively charged ions. The plasma tightens and rejuvenates the skin from the inside out.
