A Matter of Energy

  • Higher temperatures cause greater tissue contraction (figure 1)1,2,3,4,5
    • Collagen contracts predictably when exposed to heat, and higher temperatures cause greater contraction in less time
    • To be effective, subdermal tissue must be heated to a minimum of 65°C for significant tissue contraction to occur
  • Standard radiofrequency devices can’t consistently heat beyond 65°C6
    • 85°C is a more optimal temperature for tissue contraction, but most standard monopolar and bipolar radiofrequency devices can’t reach this temperature quickly enough without causing a concerning rise in skin temperature
  • Renuvion® heats to 85°C safely, allowing for optimal tissue contraction and faster procedure times1,2,3,4,5,6
    • Renuvion heats up to 85°C just long enough to cause maximum contraction of collagen and can cool back down to baseline temperatures in less than a second (figure 2)
    • The rapid heating and cooling of tissue allows for shorter application time

Safety By Design

  • The unique Renuvion energy— helium plasma and proprietary RF — allows for precisely controlled delivery of heat to tissue, with minimal thermal diffusion6,7
  • Rapid heating with near-instantaneous cooling (figure 3) allows for shorter duration of activation, and therefore less diffusion of heat to the skin6
  • Studies show that when using the recommended techniques, temperature at the surface of the skin does not rise by more than 4°C, making cumbersome external temperature monitoring unnecessary (figure 4)6

Built On Proven Technology

One of the most exciting advancements in energy technology in the past 20 years, the Renuvion system combines the unique properties of cold helium plasma with the efficiency of RF energy. This synergy enables a high degree of precision, and always with minimal thermal effect to surrounding tissue.6

Renuvion has FDA clearance for the cutting, coagulation and ablation of soft tissue during open and laparoscopic surgical procedures.8
