Treatment of Skin Laxity Using Multisource, Phase-Controlled Radiofrequency

Abstract

Regardless of age, sex and skin type, skin tightening is a common procedure requested by patients seeking cosmetic treatments to improve facial contours and skin laxity. Radiofrequency has been proven to penetrate deeper than optical light sources independent of skin color and to be beneficial for skin tightening. I previously reported on the efficacy of multisource phase-controlled radiofrequency treatment and noninsulated microneedle radiofrequency applicator with fractionated pulse mode. The evaluation process was both subjective and objective; I evaluated objectively using threedimensional color schematic representation with quantitative volume measurements. These three-dimensional results showed significant improvement after the treatments. The post-treatment volume was drastically reduced as compared to the pretreatment volume. Most of the patients reported satisfaction with the improvement of skin laxity. The advantages of these multisource phase-controlled radiofrequency treatments are their long-lasting high efficacy of tightening effects, and the reduction of discomfort and side effects. These characteristics facilitate repeated treatments as well as provide safe and effective treatment of skin tightening.

Clinical and histologic evaluation of a fractional radiofrequency treatment of wrinkles and skin texture with novel 1‐mm long ultra‐thin electrode pins

“…Moreover, as the ultrathin electrodes are not insulated, the RF energy is emitted along the entire length of the needle, resulting in effective coagulation, bulk volumetric heating, and no bleeding. 20 These findings are more pronounced with the longer 1-mm electrodes used in the current study, as compared with the previously described experience with the 0.6mm electrodes. Nonmechanical insertion also reduces the incidence of adverse events such as bleeding and posttreatment hyperpigmentation.…”

“…Insertion pain is further lessened by using ultrathin, 0.15‐mm diameter electrode pins. Moreover, as the ultrathin electrodes are not insulated, the RF energy is emitted along the entire length of the needle, resulting in effective coagulation, bulk volumetric heating, and no bleeding 20 . These findings are more pronounced with the longer 1‐mm electrodes used in the current study, as compared with the previously described experience with the 0.6‐mm electrodes.…”

A Computational and Experimental Study to Compare the Effectiveness of Bipolar Mode With Phase‐Shift Angle Mode in Radiofrequency Fat Dissolution on Subcutaneous Tissue

“…In recent years, a multisource phase‐controlled RF device (EndyMed PRO™ 3DEEP; EndyMed Medical, Caesarea, Israel) has emerged, exploiting multiple phase‐controlled RF generators, emitting RF at 1 MHz frequency, 1–65 W for skin tightening and body contouring [30]. Such a device controls the phase of the current between each pair of electrodes, forcing RF energy vertically into deep tissue locations for the repulsion of electric fields between adjacent electrodes of the identical polarity.…”

Efficacy of microneedle radiofrequency therapy in the treatment of senile purpura: A prospective study

“…Studies have investigated several topical and oral treatments for SP with variable efficacy, including topical hyaluronic acid fragments with retinaldehyde, topical heparin‐binding epidermal growth factors, topical tretinoin, subdermal injection of calcium hydroxyapatite, oral vitamin C supplementation, daily protein intake, and oral dehydroepiandrosterone. 5 , 6 , 7 , 8 Although laser surgery is effective for several dermatological conditions and is the treatment of choice to improve photodamaged skin, 2 , 5 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 few studies have evaluated the efficacy of laser surgery in SP.
