I suppose the specifics are novel enough to warrant a paper, but on a layman’s level it has been known for decades that UV ages your skin rapidly.

We can do better than "known for decades, on a layman's level" folklore and the answer actually isn't as straightforward ([1]). Recently there's even been discussion (by a Brit scientist I believe but I have no reference) on skin cancer vs more serious forms of cancer, and also about skin pigmentation playing a role here.

"known" is the wrong word. Laymen know a lot of things, like ingesting lead, radium, mercury and arsenic. Up until a couple of years ago, people "knew" that one glass of wine a day was healthy, when infact every drop is poisonous to the body.

In reverse, people thought (and too many still "know") that MSG and pasteurization is bad.

Don't use the word know, when in fact you mean "assume".

I don’t think it’s super straightforward. Another thing laymen know: Most younger people in southern Europe don’t look old.
