Does coating sunscreen nano-particles get rid of all side effects?

Maybe you can place swatches of sunscreens on your site? Up till now I’ve tested around 60 sunscreens, but I haven’t found the perfect one yet. Some have great ingredients, but I don’t like if its really white. I also have swatches of sunscreens, but I don’t know how to post pictures here..

What I do, I apply a reasonably thick layer on my hand. Let it soak in for about 30 minutes and then look at it under various angles under normal daylight, especially indirect daylight really shows if the sunscreens leaves white cast. Also wetting your skin a bit shows if the sunscreens is white. In my opinion that’s the best way to see if a sunscreen has a potential to be white in an extreme situation. Also applying it to one half of your face helps to see what difference it makes. Applying it to your whole face and looking at it with artificial light makes it very difficult to see if it’s white, and many times I had been looking like a ghost during the day without realizing, because you only see it under specific lighting. Then I have tested many sunscreens for about 4-5 weeks on one half of my face to see how my skin reacted. But after a dozen sunscreens, I haven’t found the perfect one yet. Although from what I’ve testes so far I like the Uncover Skincare Suncare SPF30 best for its ingredients, I’ve never seen a sunscreen with such good ingredients (Tinosorb, 3% Niacinamide, 1% Green Tea extract, 1% Vitamin E), but it’s extremely white on skin. And I like the Danish brand Derma Sollotion SPF30 best because its completely invisible on skin, the only downside it’s slightly shiny and it only contains Tocopheryl Acetate (vitamine E). I also like the combination of Paula’s Choice Skin Recovery SPF30 + Paula’s Choice Resist Super Light SPF30, because in combination it’s not white, not shiny, easy to apply, and it only contains physical sunscreens, the downside they do use nano particles and I believe the concentration of antioxidants is rather low. 

Well you can say what you want about Paula’s Choice products, but in general most of them don’t contain irritants and she makes many different textures. The Resist Cellular SPF25 only contains Titanium Dioxide and is too white for me. The Calm for oily skin is okay on its own, but because its white I need to apply something over it, the Resist Super Light SPF30 is tinted, but really ment for extremely oily skin. Applying the Calm for dry skin/Skin Recovery SPF30 first and then the Resist Super Light was a reasonable combination for me.

Guys prefer invisible sunscreens otherwise you have to use foundation or powder to counteract the whitecast and although I even accept using it sometimes, it can create weird moments if someone touches your face or rubs a towel on your face and make up comes off…But I will check your site..
