So if I'm reading correctly, the 207-nm ultraviolet light simply doesn't make it past the outer (dead) layer of skin.

That's not relevant, and the paper itself doesn't really measure anything pertinent either. Ionizing radiation does not cause molecular ionization that stays in one place. It generates free radicals that propagate in reaction chains. Reducing the penetration depth only increases the volumetric dose.

Correct, but I’d still like to see their data as to what the impact is to eye tissue.
