I've tried the 'natural' methods of sublocking and natural sunscreens. They suck. Yesterday I got a little burned from using a natural, organic sunscreen. I can't use the natural blocks because I'm dark skinned olive tone and it looks like white face on me. Maybe the natural, organic sunblock with work for you. I stay out of the strong sun of middday. If you are going to be out in strong sun or hazy, cloudy warm days, I'd stick with conventional sunblock of good quality or try the really good organic lines.
