Hello, Thank you for your question. This is Dr. James Fernau from Pittsburgh, Pennsylvania. J-Plasma, now known as Renuvion, is a skin tightening procedure that helps correct loose skin that will not go away with diet and exercise alone. It is beneficial to be used for skin tightening even when there is no extra fat. Renuvion combines helium plasma with a unique RF (radiofrequency) energy to provide contraction of the underlying tissues and is used under the skin. It is a minimally invasive device that patients are typically very satisfied with. There are both immediate and long-term effects with Renuvion. The effect of the treatment will continue to improve over the course of 6-9 months as the body goes through the healing process. I recommend a consultation with a board-certified plastic surgeon to determine the best plan for your desired results. Thank you and best wishes. Sincerely, James Fernau, MD FACS
