The finding was highlighted in a randomised, split-face clinical trial titled “Effectiveness of a Radiofrequency Device for Rejuvenation of Aged Skin at Home: A Randomized Split-Face Clinical Trial” published in the journal Dermatology and Therapy.
“With the aging population and their consumption demands, approaches to reduce skin aging have gained significant attention. For decades, there has been an ongoing discussion on the optimal treatment of skin aging. Radiofrequency (RF) is an important ablation method and has become a popular means of rejuvenation, prevention of regional fat loss and contour restoration,” wrote the researchers.
To test their hypothesis, the team analysed the skins of 32 healthy Chinese women aged between 35 and 60 years with crow’s feet in a randomised, controlled, split-faced trial over 12 weeks. Five repeated measurements were done, and the subjects also agreed to actively avoid sunlight exposure during the trial.
One side of the subject’s face would be randomly selected to be “the experimental side” and treated with the RF beauty device by the team, while the other was considered as control and treated with an anti-ageing cosmetic.
The anti-ageing cosmetic contained aqua, glycerol, nicotinamide, palmitoyl pentapeptide-4, Ceratonia siliqua (carob) fruit extract, sodium hyaluronate and tocopheryl acetate. The RF device was used with a gel containing various ingredients like glycerin, vitamin A palmitate, tocopherol, sodium hyaluronate, ceramide 6 II, Aloe barbadensis leaf extract, Salix alba bark extract, Chrysanthellum indicum extract and Perilla ocymoides leaf extract.
