Scurvy isn't really a vitamin problem. It's a folding problem.
Collagen is built as a long strand that has to twist into a stable triple helix. It only holds that shape if certain points get chemically modified first a reaction needing vitamin C as a cofactor and oxygen as an ingredient. Miss either and the strand folds wrong and gets destroyed before it ever becomes skin.
Everyone knows the vitamin C half. Almost nobody mentions the oxygen half.
Now look at the timescales. Your outer skin runs fast new cells form at the base, reach the surface in about two weeks, and are gone within the month. You're wearing skin that didn't exist in January.
The collagen underneath turns over across years. Structure, not surface.
Which is why a shortfall down there stays invisible. The fast layer keeps replacing itself and everything looks fine, while the slow layer quietly loses more than it builds. By the time it shows, the deficit is old.
And oxygen breaks first, because skin is last in line. Blood flow gets allocated by priority, and the organs keeping you alive outrank the one people look at.
Hyperbaric oxygen usually gets explained as more oxygen in the blood. Accurate, and not the point an hour of surplus doesn't move a system that runs on years.
What moves it is the drop. Oxygen rises during a session and falls after, and the cell answers that fall the way it answers real scarcity: it builds supply lines. New capillaries into tissue that was being served last. The shortage response, without the shortage the hyperoxic-hypoxic paradox, if you want to read the research yourself.
Better-looking skin was never the goal. Changing what the foundation can afford to build is.
