+ | The two studies Trevor cited regarding sunscreen did not use zinc oxide but the synthetic chemical sunscreens. | ||
+ | |||
+ | I find that zinc oxide at high concentrations (18-25 %) does work for me if I'm not outside a long time. | ||
+ | |||
+ | But it only blocks 90% or so of the sun's effects. | ||
+ | |||
+ | If you are outside more than two or three hours, it becomes less effective. | ||
+ | |||
+ | I also have evidence from my own experience that the zinc oxide is not absorbed significantly, | ||
+ | |||
+ | This is unlike the synthetic chemical sunscreens that break down and/or are absorbed within a couple hours of putting them on. | ||
+ | |||
+ | This supports various studies various laboratory studies of zinc oxide. | ||

+ | Joyce is correct, sunscreens are still a grey area where there is a paucity of real data :) | ||
