Is titanium dioxide in sunscreen and makeup actually safe?

Titanium dioxide sits on the skin surface rather than being absorbed, and major regulators including the FDA and EU consider it safe for topical cosmetic use at the concentrations used in products.

Why do some headlines say titanium dioxide is a carcinogen?

A classification system categorizes inhaling loose titanium dioxide powder in occupational settings, like mining or manufacturing, as potentially concerning. That inhalation exposure is very different from applying a cream or lotion to your skin. The EU restricts nano-form titanium dioxide only in spray and loose powder products specifically to avoid inhaling particles, which is a targeted precaution, not evidence that skin application is unsafe.

Why can't I buy spray sunscreen with nano titanium dioxide in the EU?

The EU restricts nano-form titanium dioxide in sprayable products as a precaution against airborne particle inhalation. You can still use creams and lotions with titanium dioxide throughout the EU.

Titanium Dioxide

Commonly feared, low concern·Strong evidence

A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.

The myth vs the evidence

Some headlines cite an international cancer classification for titanium dioxide to suggest sunscreens and makeup are risky. That classification applies to inhaling large amounts of loose titanium dioxide powder in occupational settings, not to applying it topically in a cream or lotion. The EU does restrict nano-form titanium dioxide in sprayable products specifically to avoid inhalation, which is a targeted precaution, not evidence that skin application is unsafe.

Worth knowing

Restricted in the EU

EU restricts nano-form titanium dioxide in products that could be inhaled, such as sprays and loose powders, as a precaution against airborne particle exposure.
