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

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: 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.
