My personal preference is the LAVANILA facial one. http://www.sephora.com/browse/product.jhtml?id=P26
And here are some links to the past regarding the issue (one of them isn't all naturals but has some natural picks):
Hope that helps.
I have sensitive skin and a lot of sunscreens cause a "burning" sensation on my face due to the chemical content. I have found a wonderful sunscreen that works perfectly under makeup. It's called Neutrogena Pure & Free Liquid Daily Sunblock SPF 50 and it's 100% naturally sourced. It is waterproof and sweat-proof and has the consistency of water so it absorbs very quickly and leaves no greasy residue. It gives you an even, non-shiny finish and works so great under my makeup that I can't tell that I'm even wearing a sunscreen. It is perfect for sensitive skin because it is PABA-free, fragrance-free, dye-free, oil-free and is free of irritating chemical ingredients. It is also hypoallergenic. You can purchase it anywhere that Neutrogena products are sold (Ulta, Wal-Mart, Target, etc.).
An excellent organic brand that does not irritate my skin because it has no harsh chemicals since it is 100% natural / organic is Juice Beauty. Juice Beauty's sunscreens are wonderful and come in several different formulas (all with a high SPF) from very lightweight to very moisturizing. I am going to give you the link to browse through the four different sunblocks Juice Beauty has to offer so you can choose the one that best meets your needs: http://www.sephora.com/browse/brand_hierarchy.jhtm
I hope this helps you.
