Mineral SPF Filters
Zinc oxide and titanium dioxide, inorganic filters that protect skin by absorbing, reflecting and scattering UV radiation.
Definition
What is it?
Zinc oxide and titanium dioxide are inorganic filters used in sunscreens. Zinc oxide covers a broad range of UVA and UVB wavelengths, while titanium dioxide contributes more strongly to UVB protection and part of the UVA spectrum. Actual protection is determined by the finished formula and its SPF and UVA testing.
