Revolutionary Laser Treatment Demonstrates Anti-Aging Properties Through DNA Remodeling

Groundbreaking Study Reveals Anti-Aging Potential of Candela's Nordlys® Laser

In a significant advancement in dermatological science, a recent study published in Scientific Reports has unveiled compelling evidence regarding the anti-aging effects of Candela's Nordlys® 1940 nm non-ablative fractional laser. This study, the first of its kind to provide in vivo human data, emphasizes the treatment's ability to not only rejuvenate the skin’s surface but also remodel its epigenetic signature.

The Study Overview

Conducted in partnership with Mitra Bio and the Candela Institute for Excellence, this innovative research involved a split-face study of 22 adult participants. Over the course of nine months, over 3.8 million genetic regions known as CpG sites were profiled. Notably, 83.9% of these sites were linked with skin aging and exhibited a marked shift in DNA methylation levels due to the laser treatment. Such changes are critical as they indicate biological age reversal on a molecular scale.

The meticulous analysis showcased that the treatment elicited progressive and durable changes: 635 distinctively methylated regions were identified one month after the treatment began, with noticeable expansion over the following months, which remained stable at the six-month mark. This substantial duration of effects is particularly exciting for the world of cosmetic dermatology.

Observable Improvements

Not only did the laser demonstrate remarkable molecular changes, but it also provided visible improvements to the skin. Quantitative imaging via the VISIA system revealed a median reduction of 38% in brown spots on the treated side compared to the untreated side one month post-treatment. Alongside this, simultaneous enhancements in skin texture and pigmentation were observed, suggesting that the visible benefits are closely tied to specific gene expression pathways related to skin health.

Connections to Skin Cancer Biology

This groundbreaking research extends beyond aesthetic improvements. The study highlights a potential molecular link between laser treatment and skin cancer prevention. The Nordlys® laser positively impacted DNA methylation at several critical loci involved in keratinocyte regulation, suggesting that it may help mitigate risks associated with conditions like basal and squamous cell skin cancers.

Dr. Konika Patel Schallen, the study's lead author, articulated the importance of this research, stating that it is a fundamental step in unraveling the underlying biology observed in clinical settings. Historically, dermatologists have recognized the efficacy of Nordlys treatments but lacked a comprehensive explanation for the observed improvements. This study offers a crucial scientific rationale by elucidating the molecular mechanisms contributing to healthier, more youthful-looking skin.

Scientific Credibility and Future Implications

Dr. Cristiana Banila, Chief Scientific Officer of Mitra Bio, emphasized the reliability of epigenetic patterns as markers for aging, highlighting the analysis's scientific integrity and durability over months. The implications of these results extend into the realms of regenerative medicine and skin health, setting a new benchmark for how treatment outcomes are evaluated.

Candela’s CEO, Geoff Crouse, shared enthusiasm for the company’s commitment to advancing science-based innovations in aesthetic medicine. He underscored the importance of this research in reinforcing Candela’s position as a leader in exploring the regenerative capabilities of their technology, going beyond merely superficial cosmetic treatments.

Conclusion

As this landmark study shines a light on the intricate connection between innovative laser treatments and the biology of aging, it promises to reshape our understanding of skin rejuvenation strategies. The Nordlys® laser exemplifies how advanced technological solutions can potentially lead to significant cosmetic and health benefits, presenting new avenues for safer and more effective skincare protocols. With continued advancements, the integration of molecular insights into dermatological practices may herald a new era in aesthetic treatment, pushing the boundaries of what's achievable in skin health.
