John Masters Organics SPF 30 Natural Mineral Sunscreen

While reading Time magazine last November, I came across a blurb about the very cool invention of smog-eating cement. In a town near Milan, cement was mixed with titanium dioxide, which broke down smog.  Excited, I headed to my laptop where I found this article, also about titanium dioxide's smog-reducing ability.

Both of these news stories beckon the question:  Can makeup, moisturizers, and sunscreen with titanium dioxide—a mineral sunscreen that naturally protects against UVA and UVB rays—also prevent free radical damage from pollution on our face (aka aging)?  It can't hurt to try, right?

My titanium dioxide-containing picks are Jane Iredale Dream Tint SPF 15 tinted moisturizer, Juice Beauty Green Apple Moisturizer SPF 15, and the new John Masters Organics SPF 30 Mineral Sunscreen.  It contains reparative moisturizers and humectants like aloe, shea butter, and hyaluronic acid plus antioxidant-rich green tea and healing calendula. It's lightweight but does leave a slight white cast on your face.  Happy days of sunshine this summer!
