Del-Ray Dermatologicals makes a sun block by the name of Blue Lizard. This sunblock is different from most sunblocks you can buy in the U.S. because it has UVB protection. Most sunblocks out there have protection for UVA but not UVB except for Blue Lizard. I only know this because my brother has done research on sunblocks and lives on my parent's ranch. Therefore he is doing lots of outside work and wanted maximum protection that sunblock can offer. So he embarked on a research spree and came up with Blue Lizard that protects the best. The sunblock is really good. It is thick however and you feel like you were dipped in wax but if this stuff gives you better protection then I am down with that! The Blue Lizard had a few downsides to it. For one you have to reapply it if you sweat or go swimming so be sure you do that otherwise you won't be protected. The big down side is that Blue Lizard is not accessible to the U.S. market but it is very abundant in Australia. Australians seem to swear by it! So you either have to go to Australia to get it or order it online. I know it doesn't make sense, a U.S. Dermatological company selling products in Australia but are not for sale in it's own country but I guess that is kind of how it plays out sometimes, huh? read more
