Overview of suncreen ingredients

“Titanium dioxide and zinc oxide provide UV protection primarily via absorption of UV radiation and not through significant reflection or scattering.”

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”
