Frequently asked questions

Is Titanium Dioxide a mineral or chemical sunscreen?

It is a mineral (inorganic) filter. It works primarily by absorbing UV, with some reflection and scattering, and is one of two mineral UV filters allowed globally.

Does Titanium Dioxide cover UVA?

It covers UVB and UVA2 according to the data here, but not the longer UVA1 range. For broad UVA1 protection it is typically paired with Zinc Oxide or organic UVA1 filters.

Is Titanium Dioxide approved worldwide?

Yes. It is approved as a sunscreen filter in the US, EU, and Korea up to 25%, and in Japan as a quasi-drug ingredient. It is one of the most globally accepted UV filters.

Why do some Titanium Dioxide sunscreens leave a white cast?

The filter is white in its solid form, so coverage and finish depend on particle size and formulation. Micronized and coated grades reduce visible whitening compared to larger particles.
