Radio Frequency Radio Frequency is a cosmetic treatment designed to tighten loose or sagging skin in the face, eyes, tummy, and even arms and legs, without an incision or recovery time. Radio Frequency is an energy source designed to uniformly heat the dermis (inner layer of skin). The heat is designed to tighten deeper layers of the skin while helping to initiate the production of new collagen. It also diminishes stretch marks. Radio Frequency Firming Treatment The Radio Frequency energy penetrates the skin layers to selectively heat the skin tissue, where the collagen fibers and fat cells drain then shrink, while those all important fibroblast cells are stimulated to produce new collagen and elastic fibers. The effect of this is tighter, smoother, younger looking skin. Fat cells are reduced and stubborn cellulite looks a lot less noticeable.
