Radiofrequency Combinations

Abstract

Radiofrequency (RF) may be combined with other modalities, particularly light-based treatments, to maximize the benefits of each while reducing the risks of treatment. The light energy may be used, for example, to preheat a target by selective photothermolysis. Since RF travels preferentially in warmer tissues due to reduced impedance, the combination of RF and light may allow the use of lower fluence of each. Such an approach can maintain effectiveness and improve safety. This approach has been used successfully on a variety of indications on the face and body. This chapter reviews the clinical studies reported. © 2015 S. Karger AG, BaselRadiofrequency (RF)-based devices have become a mainstay in modern aesthetic medicine and are considered to be one of the leading technologies currently available for cosmetic treatments. Their proven safety and efficacy has been extensively documented in troves of clinical trials for the treatment of a plethora cosmetic indications that include skin rejuvenation, skin tightening, wrinkle improvement, acne vulgaris, acne scarring, cellulite, striae distensae, hair removal and vascular lesions. Varying combinations of RF energy with other therapeutic modalities such as laser and light energy sources as well as mechanical tissue manipulation with vacuum and massage have also been investigated and explored in depth, and have been shown to even further improve the clinical outcomes of these cosmetic indications.elōs (electro-optical synergy) (Syneron Medical Ltd., Yokneam, Israel) was the first technology that simultaneously harnessed the power of bipolar RF and optical energy, resulting in a synergistic effect of combined technologies. The technology overcomes some of the safety and procedural limitations of intense pulse light (IPL) and conventional lasers.
