Efficacy of home‐use light‐emitting diode device at 637 and 854‐nm for facial rejuvenation: A split‐face pilot study

Abstract Background The use of light‐emitting diode (LED) in combination wavelength for facial rejuvenation has been previously reported. Nowadays, there has been a growing market for home‐use cosmetic devices because of its low cost and convenience. Aims To evaluate the efficacy and safety of home‐use LED device on facial rejuvenation. Methods This was a prospective split‐face clinical trial with a total of 24 subjects, who presented with photo aging skin. All subjects were treated with the home‐use LED device on the left side of their face, twice a week for 8 weeks. Primary outcomes measured in the study were the changes in the biophysical properties of the skin assessed with the following parameters: skin elasticity, skin hydration, texture, and wrinkles. Evaluations were done at baseline, 2‐, 4‐, 6‐, and 8‐week follow‐up. Subjects’ self‐improvement scores and adverse reactions were also recorded. Results All 24 subjects completed the study and attended all follow‐up. Skin elasticity was significantly higher in the LED group compared to the control during the 6‐ and 8‐week follow‐up ( P < .05). In the LED group, an image of the treated skin captured using Visioscan ® showed improvement of the skin texture at 8‐week follow‐up. Majority of the subjects in the LED group scored good improvement on all follow‐ups (37.5%, 41.7%, 58.3%, and 62.5%) when compared to the baseline. No adverse reactions or pain were recorded in the study. Conclusion The home‐use LED device, with a combination wavelength of 637 and 854 nm, is safe and can be used as an adjunctive treatment for self‐administered facial rejuvenation.
