*3.2.2.1 Superficial RF treatment*

For gentle treatment of mild to moderate photoaging, superficial monopolar RF, such as Thermage (Thermi) can be used. Superficial monopolar RF utilizes gentle nonablative heat delivery from skin surface to the dermis at a controlled depth to result in visible improvements in skin tightening, texture, and rhytids, as well as significant histologic increases in collagen types I and III, and neocollagenesis [16, 17]. Although consistent results are seen with this technology on the face, results are less consistent when applied to the arm in our practice and thus infrequently used.
