Titanium Dioxide (Ci 77891)
Ingredient Info
Titanium dioxide is a white mineral powder that sits on top of your skin to physically block and scatter ultraviolet (UV) rays before they can cause damage. It's commonly used as the active ingredient in mineral or physical sunscreens.
Benefits
- Provides broad-spectrum UV protection (UVA and UVB)
- Less likely to irritate sensitive skin compared to chemical sunscreen filters
- Starts protecting immediately upon application without needing to absorb into skin
Potential concerns
- Can leave a white or chalky cast on skin, especially in higher concentrations or on darker skin tones
- May feel heavy or thick in formulations
- In powder form, inhalation of particles has raised occupational safety concerns, though skincare use is considered safe
Science: Titanium dioxide is approved as a safe sunscreen active ingredient by the FDA and is considered non-irritating and photostable. The EU and regulatory bodies have confirmed safety for cosmetic use; concerns about nanoparticle penetration have been largely addressed by evidence showing minimal skin penetration of typical formulation sizes.
