Submission + - Further progress on cerium oxide as a no-compromise physical UVA/UVB protectant (nanowerk.com)
I've been impatiently following the past couple of decades of research showing “doped (i.e., in combination with certain other chemicals) cerium oxide provides excellent protection [...and] was found to look 'more natural' and 'less visible' to wearers." Plus, as noted in Chemistry World, “Unlike zinc oxide and titanium dioxide [...] these could actually scavenge the UVA-induced free radicals from skin cells."
