Overview of suncreen ingredients
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3543289/
“Titanium dioxide and zinc oxide provide UV protection primarily via absorption of UV radiation and not through significant reflection or scattering.”
https://onlinelibrary.wiley.com/doi/abs/10.1111/phpp.12214
From the FDA’s website:
“Although the protective action of sunscreen products takes place on the surface of the skin, there is evidence that at least some sunscreen active ingredients may be absorbed through the skin and enter the body”

In 2014, the FDA updated sunscreen ingredient proposal rules
