		<description>I can think of a few products that only use titanium dioxide and zinc oxide that definitely have SPF ratings written on the bottle. 

&quot;Because sunblocks reflect all the UVR, they do not carry an SPF rating.&quot;

Did that sentence even make sense? As far as I know, both zinc oxide and titanium dioxide both have excellent UVB protection and mediocre UVA protection - since SPF only measures UVB, then logically, those sunscreens containing the aforementioned ingredients could certainly carry an SPF rating.</description>

		<description>Energy - micronized ingredients, especially in mineral makeups, can be harmful b/c your skin absorbs it into your bloodstream.</description>

		<description>&quot;Sunblocks contain zinc oxide, titanium dioxide, kaolin, talc or iron oxide. And they are opaque, like the white stuff lifeguards put on their noses.&quot;

not if they are micronized.</description>

		<description>You could also try the Colorscience Sunforgettable SPF30 powder. I have it in clear, and I also keep a Neutrogena spray for my body.
And, yeah I have a parasol and hats, otherwise my Irish-French skin turns lobster red. :)</description>

		<description>They do make sunscreen in spray bottles. I use it all the time over my make-up and it works great! Look for it at drug stores where you would purchase regular sunscreen.</description>
