Titanium DioxideBenefits, how to use & safety
The other mineral filter, strong where it counts.
What is Titanium Dioxide?
Titanium dioxide is a mineral UV filter that works by reflecting and scattering light. It is excellent against UVB and shorter UVA rays, and it is usually paired with zinc oxide for fuller broad-spectrum coverage.
How it works
Titanium dioxide particles physically scatter UV on the skin surface. Because they protect less in the longest UVA wavelengths, sunscreens often combine them with zinc oxide.
Key benefits

Frequently asked
Is titanium dioxide safe?
In creams and lotions on skin, yes. Avoid inhalable powder or spray forms.
Zinc oxide or titanium dioxide?
Zinc oxide covers the full UV range. Titanium dioxide is strong in UVB and shorter UVA, so combining them is common.
Does it cause white cast?
It can, but modern formulations reduce it.
