Side note--- The SPF rating *ONLY* applies to UVB rays which causes burns. It does not apply to UVA which is more responsible for skin cancer and wrinkles.

To block UVA better, look for newer products containing mexoryl, or else ones containing zinc oxide. Neutrogena claims their helioplex blocks UVA longer too.
