This study presents a research study evaluating the effects of hyperbaric oxygen therapy on skin aging in a normal aging population through skin biopsies and various physiological assessments.
Key Findings on Skin Aging 13
The study revealed significant histological changes in the skin of participants after HBOT, indicating its potential to reverse some aging effects. 14
- No changes in elastic fiber density or thickness were noted, but fragmentation decreased significantly (90% high fragmentation to 10% post-HBOT). 15
- Collagen fiber density increased significantly from 67.84±10.98% at baseline to 76.61±9.52% post-HBOT.
- Papillary layer thickness decreased significantly from 133.22±22.42 μm to 106.60±31.01 μm after HBOT.
- The number of blood vessels increased from 24.00±15.72 to 33.40±12.28 post-HBOT. 17
Mechanisms of Action
The study suggests that HBOT may exert its effects through mechanisms such as angiogenesis and clearance of senescent cells, which are critical in the aging process. 18
- HBOT induced angiogenesis, evidenced by increased CD31 intensity (625.81±394.29 post-HBOT). 19
- The number of senescent cells decreased significantly from 3.14±1.06 to 2.48±1.23 after HBOT. 7
- The study highlights the role of hypoxic-induced factors (HIFs) in promoting angiogenesis through HBOT. 20
Conclusion
Therefore, in this study, Hyperbaric oxygen therapy (HBOT) has been shown to significantly improve skin aging in a healthy aging population by enhancing collagen density, elastic fiber length, and reducing aged, senescent skin cells.
This study is the first to demonstrate these effects in humans, indicating potential therapeutic benefits of HBOT for skin aging.
