First off, my disclaimer: I am not familiar with what sunscreen ingredients are considered natural and/or safe. I simply picked this stuff up because it's by Kiss My Face (a fairly reliable and cheap natural brand) and it comes in a spray bottle. The active ingredients are Homosalate, Octisalate, Octinoxate and Oxybenzone, all of which are listed as giving either sun protection or extending the duration of the sun protection. The bottle says it blocks both UVA and UVB rays, is fragrance free and retains it's SPF after 40 minutes in the water. I do notice that propylparaben is listed as an inactive ingredient though. I have always had a bit of a fascination with spray sunscreen, and the fact that this was made by a natural brand ensured that I would end up buying it. I use it mostly on my arms and use it nearly everyday. It's more like a spray oil, which I like because there's no white-chalky stuff to rub, rub, rub in. Instead this can be smoothed into your skin and then left for about 5 minutes while it absorbs. I don't use it on my face, I think it would be way too greasy. Here's why I love it though, it makes my skin so smooth and soft when I spray it on! I have acne-like KP on my upper arms and this stuff makes my skin there look super-good. And the texture feels smooth and moisturized, like I applied a body oil instead of sunscreen. Because of this, I have no trouble remembering to apply it everyday, and this is the first sunscreen where I've been able to say that. It does have a light sunscreen smell, but it's not too heavy or lingering. The spray can be messy, so I just apply it in the shower before I get dressed. A couple of sprays and I'm good to go. I used to notice my arms getting warm when the sun hit them when I was driving in my car, but now when I wear this sunscreen I no longer get that. Good stuff that will definitely stay in my beauty cabinet and be packed along on my summer vacations.
