A Promising Step Towards Non-Invasive Facial Rejuvenation
The global demand for minimally invasive cosmetic procedures to combat skin aging is on the rise. One innovative approach, Photobiomodulation (PBM), involves using light-emitting diodes (LEDs) to improve collagen synthesis, which in turn, helps in facial rejuvenation. While red PBM has been studied in clinical trials, a comparison of the effectiveness of different wavelengths at the same light dose for reducing periocular wrinkles (wrinkles around the eyes) has not been performed until now.
A recent randomized controlled trial published in ‘Photobiomodulation, Photomedicine, and Laser Surgery’ (Mota et al, 2023 PMID: 36780572) aimed to evaluate the effectiveness of red and amber PBM protocols for facial rejuvenation. The study involved 137 women, aged 40-65, with skin phototypes II-IV and Glogau photoaging scale types II-IV. Participants received 10 sessions of red (660 nm) and amber (590 nm) PBM (3.8 J/cm2) on each side of the face over four weeks. Outcomes measured included periocular wrinkle volume, skin hydration, skin elasticity, and quality of life.
The results were promising, with a significant reduction in wrinkle volume observed after both red (31.6%) and amber (29.9%) PBM treatments. However, neither treatment improved skin hydration and viscoelasticity. Importantly, both questionnaires used in the study indicated improvements in participants’ quality of life.
Despite being a single RCT and not a systematic review, the study underscores the potential of both red and amber PBM as effective, non-invasive tools for facial rejuvenation, reducing wrinkle volume by approximately 30%. This makes PBM a strong potential option for patients with diabetes or keloids, conditions for which highly inflammatory rejuvenating procedures are not indicated.
While the study findings are encouraging, it is essential to consult with a healthcare professional or a specialist in photobiomodulation before starting any new treatment regimen.
