Radiofrequency therapy uses currents similar to the ones found naturally in our body’s electrical circuits to cause tissues to contract, which in turn safely tighten skin and increase its contour. When the body creates resistance to the currents, heat is generated, which strengthens and refines the underlying tissues. Because of the ability of radiofrequency to reach the dermal layer of the skin, the skin is made firmer while existing collagen fibers are strengthened and the production of new collagen proteins are stimulated. All of this is done fractionally (in tiny pin-points), having great effects but not requiring a long time for the skin to heal.
