Great link. Some interesting info... years ago, the Oz gov't would only let sunscreens/blocks be labelled "15+" as a maximum, as the argument was that people would get careless if wearing higher rated ones and not wear hats/shirts etc. Now they label them at their true SPF, meanwhile the US gov't is going the other way!
I see two that I thought were OK get a guernsey on the ski mag tests (Dermatone and the Rocky Mountain stuff). I use Dermatone to protect the face against wind/extreme cold, but its sunscreen abilities are always welcome.
It was interesting how they commented about "rubbing it in" on many of the tests. To get full effectiveness from sunscreen, you want to coat the face thoroughly with the cream, but rubbing it in is not beneficial. The cream needs to dry as a coating on your skin. I usually put a thin layer on after my morning facewash, let it dry over breakfast, and then I smear a thicker layer on over the top. It usually looks white, but as it dries, the white stuff disappears.
I guess if you have darker skin, and don't have skin cancer in the family, it won't matter so much. In Oz, skin cancer is endemic across much of the population. I wear sunblock every day of the year.
