The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

The HBOT cohort in the study experienced a significant increase in collagen fiber density (average collagen density: 67.9% control vs 76.6% HBOT) (3). This change also coincided with a decrease in the thickness of the 2nd outermost layer of the skin, another marker of rejuvenation since this layer increases in thickness with age (3).
