Handmade V-FC combines RF and blank for face contour

A new handmade V-FC, which uses radiofrequency (RF) and vacuum technology, was found effective and safe for non-surgical outline of the face.¹ RF -based devices are known to reduce fat, collagen production, stimulate fibroblasts and increasing blood circulation.² The V-FC hand combines bipolar divestment optimized radiofrequency energy technology (core) with vacuum suction and targets different tissue depths at varying frequencies, creating a synergistic effect on the tissue.

“With the utilization of basic technology, the professional is able to provide flexible, accurate and specific treatments both for reducing facial contour and for regional reduction,” the authors write.

The Multicenter Retrospective Study was conducted in 3 clinics between November 2019 and January 2024 (Mimi Ehrenraich Aesthetic Clinics, Israel, Wolf Aesthetic Center, Israel and Sinclair at home). Participants (n = 33) had aging face with mild to severe skin relaxation and/or local fat accumulation. They were all women aged 23 and 80 years (average: 51 years) with Fitzpatrick skin photocopies between II and IV. BMI ranged from 21 to 35 with an average of 26.

The device was used once a week in patients for 3 to 6 sessions. About half of the participants completed 4 sessions, but 30% made 3 sessions, 9% made 5 sessions and 12% made 6 sessions. Phone calls and follow -up e -mails lasted between 3 and 52 months, depending on the date of the last treatment.

The researchers measured demographics, safety, skin looseness according to the skin rating scale and the rate of improvement on a 4 -point subjective scale. A blind evaluator received before and after pictures and was asked to sort them. EX NINO depth penetration and histological analysis in vivo were also used.

Of the 33 sets before and after images, the blind evaluator correctly found 91%. Average skin relaxation decreased by 34% at a moderate rate of improvement (1.7 ± 1.1). The basic degree of purity of the skin was 1.9 (moderate), which was reduced to 1.3 (mild), according to the Laxity Skin scale. There was no correlation between demographic elements, such as skin type, age and BMI, and LAXITY degree change. There was also no relationship between the number of treatments and the change in relaxation. However, a moderately positive association was found between the patient’s BMI and the number of treatments (P. <0.05).

EX vivo results showed that the average minimum penetration depth was 3.2 mm while the average maximum penetration depth was 11.3 mm. No signs of acute damage were observed in any treatment regulation, even the highest power, in Vivo evaluation. There were no burns, bleeding, skin rejection or other texture damage. In addition, the number of filaments and fibroblasts increased 4 weeks after treatment.

Short -term or long -term side effects were not recorded during treatment or during follow -up. The immediate response of the skin after treatment included mild erythema and occasional edema, which was expected. BMI and weight did not change 4 weeks after treatment.

The homogeneous, small sample size, short monitoring and lack of control group are potential study restrictions. The most comprehensive and different research can emphasize the value of this device.
