FAQ
Is Renuvion a laser or radiofrequency?
Dr. Oh’s answer
It uses radiofrequency energy, but it’s different from radiofrequency lifting applied to the skin surface. A thin handpiece goes under the skin, and plasma created at its tip heats the fibrous tissue directly.
Plasma is a gas that has been given enough energy to carry an electric charge. The glow inside a fluorescent light is also plasma.
Renuvion produces heat in two ways. Heat is released as helium turns into plasma and then back into gas, and the radiofrequency current passing through the plasma also leaves heat in the tissue. The heat covers a small area for a very short time, so the treated spot cools quickly.
Lasers send light, and ultrasound and radiofrequency lifting send ultrasound or electric current, from the skin surface inward. With Renuvion, the tip that produces the heat sits under the skin, so it heats the fibrous tissue directly without passing through the outer skin.
