Thanks for the source, I looked at some of the studies and it seems like you were correct but there appears to be a small catch. There seems to be a difference between physical blockers such as TiO2 and ZnO, which basically reflect the UV rays and UV-absorbers like mentioned in your link which convert the rays to heat. Sunscreen usually contains both components. Interesting stuff though, I thought sunscreen was mostly a solved problem but you and your reference as well as some other references made me rethink that idea.
