In the quest for youthful skin, a groundbreaking study has shed light on the potential of photobiomodulation therapy to turn back the clock on facial aging
A new study has found that red and amber light therapy can reduce periocular wrinkle volume by approximately 30% after 10 sessions over 4 weeks, offering a minimally invasive option for facial rejuvenation.
In the relentless pursuit of youthful skin, researchers have uncovered a promising new approach to combat the signs of aging. A recent randomized controlled trial, conducted by Mota et al. and published in Photobiomodulation, Photomedicine, and Laser Surgery, has demonstrated that red and amber light therapy can significantly reduce periocular wrinkle volume, offering a minimally invasive alternative to traditional rejuvenation procedures.1 The periocular region is the feature rich region around the eye which may include features like eyelids, eyelashes, eyebrows, tear duct, eye shape, skin texture and more.
The study, which recruited 137 women aged 40-65 with skin phototypes II-IV and Glogau photoaging scale types II-IV, aimed to evaluate the efficacy of red (660 nm) and amber (590 nm) photobiomodulation (PBM) protocols for facial rejuvenation at the same light dose of 3.8 J/cm2.1 Participants received 10 sessions over a period of 4 weeks, with one wavelength applied to each side of the face.1
Photobiomodulation therapy, also known as low-level laser therapy, has gained attention in recent years for its potential to stimulate collagen synthesis and improve skin health.2 While previous in vitro studies have shown promising results for both red and amber PBM in enhancing collagen production, this study is the first to directly compare the effects of different wavelengths at the same light dose in a clinical setting.1
The primary outcome measure was the reduction in periocular wrinkle volume, assessed using VisioFace® RD equipment.1 Secondary outcomes included skin hydration, measured by the Corneometer CM 825; skin elasticity, evaluated using the Cutometer Dual MPA 580; and quality of life, determined by adapted versions of validated questionnaires (MelasQoL-BP and Skindex-29).1
The results were remarkable, with both red and amber PBM achieving significant reductions in wrinkle volume - 31.6% and 29.9%, respectively.1 While neither treatment improved skin hydration or viscoelasticity, participants reported improvements in quality of life based on the questionnaire responses.1
These findings have far-reaching implications for the field of aesthetic medicine, particularly for individuals with diabetes or keloids, conditions that may preclude them from undergoing more invasive, inflammation-inducing rejuvenation procedures.1 The study's authors emphasize the potential of PBM as an effective tool for rejuvenation, offering a safer alternative to traditional treatments.1
As with any scientific research, it is essential to consider the study's limitations and the need for further investigation. While this trial provides compelling evidence for the efficacy of red and amber PBM in reducing wrinkle volume, additional studies with larger sample sizes and longer follow-up periods may help to confirm and expand upon these findings.
In conclusion, this groundbreaking study has shed light on the promise of photobiomodulation therapy as a minimally invasive option for facial rejuvenation. By harnessing the power of red and amber light, individuals may now have a safer, more accessible means of achieving youthful, radiant skin. As research in this field continues to evolve, the future of aesthetic medicine looks brighter than ever.
