Thermage The newest technology to reverse the signs of aging uses radiofrequency to lift and tighten sagging skin. This radiofrequency gently heats the deep surface of the skin causing it to contract and tighten. This lifts the face, brow and cheeks without surgery and without downtime. The procedure is safe and requires less than one hour. Only topical anesthesia is used and patients return to work or play immediately following a treatment.
