Why you should care.
Titanium dioxide in nanoparticle form (<100nm) used in sunscreens to eliminate the white cast of traditional mineral sunscreens. While non-nano titanium dioxide is considered safe, the nanoparticle form raises concerns about cellular penetration, inhalation risks, and potential DNA damage.
Top Health Concern
Nanoparticles can generate reactive oxygen species (free radicals) when exposed to UV light, potentially causing DNA damage.
