In a 2021 study on healthy older adults, hyperbaric oxygen therapy (HBOT) was shown to improve skin quality at a cellular level. Over a 3-month treatment period, participants experienced increased collagen density, longer elastic fibers, and improved blood vessel formation—alongside a measurable reduction in senescent (aging) cells. These results suggest HBOT may offer a novel, evidence-based approach to managing the visible and biological effects of skin aging.
Study Overview
Title: The Effect of Hyperbaric Oxygen Therapy on the Pathophysiology of Skin Aging: A Prospective Clinical Trial
Quick Summary: This prospective clinical trial evaluated how HBOT affects aging-related changes in the skin of healthy older adults. Skin biopsies taken before and after a 3-month HBOT protocol showed improvements in structural integrity, blood vessel formation, and reduction of aging markers at the cellular level.
Key Findings:
Collagen density increased significantly (p < 0.001; effect size = 1.10)
Elastic fiber length improved (p < 0.0001; effect size = 2.71)
Blood vessel density increased (p = 0.02; effect size = 1.00)
Senescent cell count decreased (p = 0.03; effect size = 0.84)
No change observed in elastic fiber thickness or density
Study Details:
Sample Size: 13 healthy male participants (mean age: 68.1 ± 2.5 years)
Study Period: 2016–2020
HBOT Protocol: 60 sessions (5 per week for 3 months) at 2.0 ATA, 100% oxygen, 90 minutes per session
Control Period: 3 months of no intervention prior to HBOT
Biopsy Measurements: Collagen (Trichrome), elastin (Orcein), blood vessels (CD31), and senescent cells (lipofuscin)
