Answer:
When choosing your natural sunscreen, you have two options; those with nanoparticles and those without. The difference between the two will show up on your skin.
Both titanium dioxide and zinc oxide are approved by the FDA as natural sunscreening ingredients. They each give broad-spectrum UV protection, although titanium dioxide works best when combined with zinc oxide or another synthetic sunscreen ingredient.
Zinc oxide and titanium dioxide work by reflecting UV rays away from the skin, shielding the skin from the sun. And they're very effective.
In their regular, non-nano sized form, zinc oxide and titanium dioxide are quite white. When incorporated into sunscreen, they'll leave an obvious opaque white film across the skin. Think of the stereotypical lifeguard with white across the bridge of the nose—yep, that's zinc oxide.
Enter nanoparticles. Sunscreen made with micronized zinc oxide and titanium dioxide rub into the skin much better, and won't leave behind a pasty look. The ultra-fine nanoparticles make the sunscreen less opaque but just as effective.
