+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.  If you are out 5 or 6 it is almost like you didn't wear it because of the % of the light that gets past the sunscreen.
+I also have evidence from my own experience that the zinc oxide is not absorbed significantly, since if I don't wash it off, it continues to work for days.  Yet briefly washing one's hands for instance means the effect is gone.
+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.  I know Trevor is skeptical about the absorption, but since my experience agrees with the studies, I tend to think they are correct.

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