Klotho Protein as a Topical Therapy for Facial Photoaging Using Combined Delivery Technologies

Area of Science:

• Dermatology
• Anti-aging research
• Molecular biology

Background:

• Klotho, a protein associated with longevity, exhibits anti-aging properties by combating oxidative stress and maintaining cellular balance.
• In vitro studies demonstrated Klotho's ability to reduce UV-induced DNA damage and enhance skin cell longevity markers.
• This research investigated the synergistic effects of a multi-product Klotho regimen on visible skin aging.

Purpose of the Study:

• To evaluate the efficacy of a combined topical Klotho regimen in improving visible signs of facial photoaging.
• To assess the impact of the Klotho treatment on specific photodamage parameters such as dyschromia, wrinkles, and skin texture.
• To determine the safety and tolerability of the 3-product Klotho regimen over a 16-week period.

Main Methods:

• An open-label, 16-week study was conducted on adults aged 25-75 with Fitzpatrick skin types I-IV and mild to severe facial photodamage.
• Participants applied a daily regimen consisting of a face serum (25%), eye serum (15%), and night cream (10%), all containing Klotho.
• Clinical photodamage scales, along with assessments for dyschromia, erythema, dryness, peeling, lines/wrinkles, and atrophy, were used to measure outcomes.

Main Results:

• Significant improvement in overall facial photodamage was observed, with an average reduction of 48.0% from baseline after 16 weeks (P < 0.001).
• All participants showed clinical improvement, with visible results starting by week 4 and progressing throughout the study.
• Statistically significant reductions were noted in dyschromia (31.2%), lines/wrinkles (27.3%), dryness/scaling (61.9%), and peeling (83.3%).

Conclusions:

• The 3-product topical Klotho regimen is safe, well-tolerated, and effective in treating multiple signs of photoaging.
• Early and progressive improvements in skin photodamage suggest that topical Klotho offers significant anti-aging benefits.
• The findings support further investigation into topical Klotho formulations for managing age-related skin concerns.
