Thanks for posting this, Suzan.
It's so hard to find a good sunscreen. I was on a quest last year for a physical ( non-chemical ) sunscreen that didn't contain nano or micronized zinc oxide or titanium dioxide. I finally found Marie Veronique sunscreen
Moisturizing Face Screen, SPF 30 - No tint
It's pricey, but I just use it for my face. It contains non-micronized zinc and no vitamin A. Plus it has green and white tea and beneficial oils. I love this one! It's not at all heavy or greasy and doesn't leave a white cast.
For the rest of my body ( on days when I'm in the sun for a prolonged time ) I was using Mexitan, but it was heavy and left a white cast, and it contained vitamin A. So I switched to Elemental Herbs sunscreen

Just recently I've been experimenting with using Red Raspberry Seed Oil, which some studies have indicated may provide a potential SPF of between 28 - 50. I've been adding it to my DIY vitamin C serum that I apply all over. So far I've yet to burn, but I haven't tried it in prolonged sun exposure yet.
