This won’t lead to people using less lotion, but it will lead to fancy lotions adding “OH precursors” as the new science buzzmarketing term

Which is funny since the exact opposite, anti-oxidants, have been a fad to add for the past 20years.

You eat anti-oxidants. So unless you're eating your lotions this isn't related and can't be the opposite.

Skin absorbs. So it's at least partially related.

If an actual nutritionist says you can eat it every monkey in a lab coat knows they can sell it as a lotion with substantially less work than testing something else.

> unless you're eating your lotions

Buddy of mine did research in Milan on common sunscreen ingredients. In a lab, those chemicals didn't tend to cross the dermis.

But put that person in the sun and you find detectable quantities of those chemicals in serum within minutes. Turns out the flushing (i.e. rushing of blood to the skin, in particular, to the surface of the dermis) increases permeability. Nobody really tested those chemicals for intravenous use.

So in a very real sense, you ingest in all but digestion the ingredients in your lotions.
