My office tested Ulthera and Thermage and compared it to Yag laser neck tightening and found the Yag laser to be more effective, and much faster and less painful. Until now, I would not recommend anything other than the Yag laser for non-surgical saggy skin tightening. The Thermi-RF is a newer device which employs radiofrequency heating with a subcutaneous probe. It achieves neck tightening and can be used to tighten saggy body skin anywhere - abdomen, arms, legs, sides, breasts. The treatment is done with local tumescent anesthesia.
Thermi RF...it is the next best thing after the surgical neck lift!
