Hi Amy,
Avene is a line for sensitive skins, that Fawnie mentioned, and here in Canada they have 2 kinds of sunscreen in their line - the regular one and one that is completely physical (no chemicals). But the downside of physical is that it sits more on your skin and also can turn white. but most people who have reactions to sunscreen are OK with this line. It seems like your issues with sunscreens are that you don't care for their textures and odors. The problem is, the higher you go in the SPF the heavier the lotion becomes (generally). SPF affects the texture of a product. That is why you won't find SPF higher than 15 or 20, usually, in a foundation. Because it changes the texture. Also, most face lotions are 15 or 20 spf for same reason. But There are a few options to consider. Avene has a makeup with a 50SPF in it that is quite sheer, amd also a makeup with a 30 SPF (this one is more like a regular makeup whereas the other one is more sheer). The quality of this SPF is high quality as well, because not all sunscreens are created equal. I am not sure where you live, but Biotherm's sunscreens are BEAUTIFUL textures for the face (or body) and are a high quality sunscreen. Lise Watier just came out with a 30SPF face lotion that is light weight. La Roche Posay's 60SPF is actually quite OK on the face - not too heavy at all, and I have oily skin, and found it OK. Vichy is another good one as well. Look for Mexoryl as Fawnie said. L'Oreal owns Vichy and Biotherm, and have had Mexoryl in their sunscrens and recently put Mexoryl XL in. So bascially, you can wear their sunscreens all day without re-applying as the ingredients don't break down.
