4% Zinc? How can this claim to be Broad Spectrum SPF 50? Disregard the Titanium Dioxide. Titanium Dioxide is NOT broad spectrum. If you truly want to be protected from UVA as well as from UVB, and you really want a mineral sunscreen, look for 18% and higher (the limit by the FDA is 24 or 25% Zinc) of Zinc Oxide. There are Titanium Dioxide-free formulas out there. Personally, I've given up on US Sunscreens. This is a US sunscreen. The SPF number always refers to UVB protection. In the US, when they say Broad Spectrum it has to meet some extremely low bar of UVA protection. Elsewhere in the world they have UVA ratings like PA or PPD, and a max of ++++ to indicate the strength/length of protection. Personally I've found a source for an international SPF with a PPD rating of 42, which means it will protect me from UVA for seven hours. Sniff. There is not one single US made sunscreen that can claim a PPD like that. (Europe is so far ahead of us on sunscreen... it's like the dark ages here.)
