Natural, Mineral-based sunblock

I finally went into one of my local health-food shops to find some sunblock that wouldn't leave me feeling gross. It's all minerals and essential oils. So far it's working, but I am not really putting it to the test. I am trying to keep to the shade during peak hours and all that fun stuff. My face is still all freckles and my nose seems to always be a little bit pinker than the rest of my face. But no burns yet! The grass at Trinity is starting to yellow in patches because we've had so much consistent sun without much rain. It's kinda sad to see. It makes me think of the drought years in California.
