Titanium dioxide exceeds this range of protection but depending on whose research you read it either performs as well as or slightly below zinc oxide It's true that titanium dioxide does not rank as high for UVA protection as zinc oxide it ends up being a small difference (think about it like being 10 years old versus 10 years and 3 months old)
