A 2021 prospective trial measured skin biopsies before and after HBOT and documented significant increases in collagen density, elastic fiber length, and blood vessel count, alongside senescent-cell clearance — direct dermal evidence of regenerative effects.

Skin & Collagen.
Hachmo et al., 2021 (Aging) is the only published HBOT trial with skin biopsies as primary outcomes. n=13 male participants. Collagen density effect size 1.10 (p<0.001), elastic fiber length effect size 2.71 (p<0.0001). Authors also reported no change in elastic fiber density or thickness — the page reflects this null finding alongside the positive ones.

The skin & collagen prescription.
The standard Saturate protocol for skin & collagen follows the cited trial below — the most widely-referenced study for this condition. The card to the right shows the base parameters drawn directly from it.
Your personalized version will adjust based on chronicity, prior HBOT experience, age, and any contraindications flagged in screening. Most adjustments are minor — pressure caps, ramp-up modifications, slight course length changes — but they materially affect safety and outcome.

What the literature documents at each stage.
Below is what published trials report at each phase of the skin & collagen protocol. Individual results vary — these are the documented patterns from the named cohorts, not predictions of your outcome.
Sessions 1 — 5
Adjustment & acclimation.
Body adjusts to pressurized oxygen. Most participants report no acute changes — early sessions establish safety patterns and chamber familiarity.
Per published protocolSessions 5 — 20
Subjective changes begin.
Reported improvements in sleep quality, energy, and mental clarity start to emerge. Quantitative testing has not yet shown statistically significant change at this stage in published trials.
Mid-protocol observationsSessions 20 — 40
Measurable changes documented.
Standardized assessments show statistically significant improvement in published trials at this stage. Imaging (SPECT, DTI, fMRI) documents biological correlates of the clinical changes.
Per cited trialsPost-protocol
Effects persist.
Gains documented at end of protocol have held at 6-month follow-up in published cohorts. Some sub-domains continued improvement after the protocol ended.
