ThermiSmooth is a procedure for improving the appearance of aging skin through tightening and increasing collagen production over a period of time. It uses a unique hand piece to deliver targeted heating to the surface of the skin. The collagen under the skin will shrink when sustained heat is applied to it above 40ºC. This initiates a process where the skin begins to tighten and the effects of aging are reduced. The hand piece delivers this heat in a controlled manner to maximize patient comfort. ThermiSmooth can treat many different areas of the face and is well suited for under the eyes, around the mouth, the forehead, eyelids, and neck.
