I don't think your research is very thorough...You realize that most sunblock only keeps you from getting tanned, it doesn't keep you from damaging your skin. The only way to truly protect your skin is to wear clothing or coat your skin with zinc oxide, if you can still see your skin, IT'S NOT PROTECTED FROM SUN DAMAGE! Try testing the effectiveness with UV beads, you can buy them at some craft or hobby stores. Apply the cream and expose to the sun, if their color changes, their not protected! Most creams do absolutely NOTHING!
