Abstract

A method for skin treatment comprises the steps of delivering at least one pulse of radio frequency power to at least one electrode in order to create an electric field; passing gas through the electric field in order to form plasma from the gas; and applying the plasma to the surface of skin. The amount of radio frequency power may be relatively low such that the application of plasma causes denaturation of collagen within the collagen-containing tissue beneath the skin surface, which may promote the generation of new collagen within the collagen-containing tissue.
