The finding was highlighted in a randomized cleft face clinical trial titled: “Effectiveness of a radiofrequency device for rejuvenating aging skin at home: a randomized cleft-face clinical trial”published in the journal Dermatology and Therapy.
“With the aging population and their consumption demands, approaches to reduce skin aging have received a lot of attention. For decades there has been an ongoing debate about the optimal treatment of skin aging. Radiofrequency (RF) is an important method of ablation and has become a popular means for rejuvenation, regional fat loss prevention and contour recovery,” the researchers wrote.
To test their hypothesis, the team analyzed the skins of 32 healthy Chinese women between the ages of 35 and 60 with crow’s feet in a randomized, controlled, split 12-week trial. Five repeated measurements were taken and the subjects also agreed to actively avoid sunlight during the trial.
One side of the subject’s face would be randomly selected as “the experimental side” and treated by the team with the RF beauty device, while the other side was considered a control and treated with an anti-aging cosmetic.
The anti-aging cosmetics contained aqua, glycerol, nicotinamide, palmitoylpentapeptide-4, ceratonia siliqua(carob) fruit extract, sodium hyaluronate and tocopheryl acetate. The RF device was used with a gel containing various ingredients such as glycerin, vitamin A palmitate, tocopherol, sodium hyaluronate, ceramide 6 II, Aloe barbadensisleaf extract, salix albabark extract, Chrysanthellum indicum extract and ocymoid buttonleaf extract.
Outcomes were measured by facial and neck signs, such as forehead wrinkles, crow’s feet, pigmentation spot density and ptosis. Lower scores correspond to better skin. The participants also had to undergo a self-evaluation.
For crow’s feet, on the experimental face side (using the RF device), the mean roughness showed a statistically significant decrease after the second, fourth, eighth and 12eweek.
In terms of skin hydration, the mean values on both sides increased after the fourth, eighth and 12etreatment week, but there was no significant difference between the two sides after treatment.
The gloss of the skin due to the gloss value of the light reflection was measured with a Glossymeter GL200, with statistical improvements observed on both sides at the same time points. However, there was a significant increase on the experimental side compared to the control side.
Explaining the results, the researchers showed that 12 weeks of continuous use of the cosmetic increased the moisture content and radiance of the skin, improved wrinkles and reduced color spots. However, wrinkles, spots and skin thickness improved more on the device side than on the control side.
While the gel on the device side contains more active ingredients than the cosmetic, the gel was only applied to the area when the device was in use and washed off immediately after use. The purpose of the gel was to achieve an even heat conduction.
“In the future, it is essential to ensure that home beauty devices are sufficiently safe to protect consumers, and their effectiveness should be fully evaluated. In addition, future studies should include long-term follow-up to assess the long-term efficacy of home beauty devices and the persistence of their effects,”the researchers concluded.
Ecolite Wellbeing (GD) company provided the home RF beauty devices for the study and funded the magazine’s Rapid Service Fee.
