Noninvasive Facial Volume Harmonization Using HIFES and Synchronized RF Technology: A Retrospective Study

Age-related facial volume loss results from changes in skin, muscle, and fat distribution, leading to sagging and contour alterations. Traditional volume restoration techniques, such as dermal fillers, carry risks and require skilled application. Facial muscle electrical stimulation combined with synchronized radiofrequency (RF) offers a noninvasive alternative.

This study evaluates the volumetric effects of facial muscle electrical stimulation with synchronized RF for facial rejuvenation.

A retrospective analysis was conducted on 43 subjects (5 males, 38 females, aged 57 ± 12). Treatments consisted of four 20-minute sessions of facial muscle electrical stimulation + RF, with follow-ups at 1 and 3 months. Facial volume changes were assessed using 3D imaging systems. Patient satisfaction and comfort were recorded using questionnaires.

At 3 months, zygomatic volume increased by +3.3 mL ( p < .001), while mandibular volume decreased by -2.3 mL ( p < .001). The net volume shift was 5.6 mL. Patient satisfaction was 94.6%, with minimal discomfort (visual analog scale: 1.6). No adverse events were reported.

Facial muscle electrical stimulation with synchronized RF effectively restores facial volume noninvasively, offering a safe alternative to traditional fillers and surgery.
