Nonsurgical Facial Contouring With a Novel Radiofrequency and Vacuum Device: A Multicenter Retrospective Study With 33 Patients.
Article in Journal of cosmetic dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe aging process reflects decreased tissue elasticity and a rearrangement of subcutaneous volume, resulting in superficial wrinkles and three-dimensional changes in skin topography. Radiofrequency (RF)-based approaches have become increasingly adopted in recent decades due to their relatively short downtime and significantly reduced risk of adverse effects.
aimsThe aim of this study was to evaluate the safety and efficacy of the V-FC handpiece through a multicenter retrospective study as well as ex vivo and in vivo analyses.
methodsThe V-FC handpiece was used once a week for a treatment course of 3-6 sessions. The clinical evaluation of 33 patients included demographics, BMI, assessment of skin laxity, and rate of improvement. An ex vivo study with porcine tissue assessed the penetration depth of RF, while device performance was evaluated in an in vivo animal histological analysis.
resultsNo significant adverse effects were recorded during the treatment course or at short- and long-term follow-ups (1, 3, and 52 months). The average skin laxity grade baseline was 34% lower at the end of the treatment course, with the average rate of improvement assessed as moderate. The ex vivo minimal and maximal penetration depths were 3.2-11.3 mm (±10%). The in vivo histopathological analysis showed no signs of acute heat injury at any treatment setting, including the maximum RF power. Additionally, staining showed a power-related progressive proliferation of fibroblasts, elastin fibers, and neocollagenesis, which was significantly higher 4 weeks after treatment.
conclusionsThe new RF device demonstrates an effective treatment for facial contouring with a proven short- and long-term high safety profile.
