I started using a mineral type this season, which can be hard to find. It is white and stays that way making you look like a ghost.

The mineral suncreens are zinc oxide and titanium oxide nanoparticles, the "white" ingredients of white paint, and the oldest sunscreens. They scatter UV instead of absorbing it like the chemical ones do. So using this is basically painting your skin white. If you can see skin, it's not enough .. Or they add enough other ingredients (oils, etc) that absorb the rest of the UV, so you're back to chemical absorption.
