CI 77891 (Titanium Dioxide)
Ingredient Info
Titanium dioxide is a naturally occurring mineral that acts as a physical UV filter and colorant in skincare products. It sits on top of your skin to block and scatter both UVA and UVB rays, making it a key ingredient in mineral sunscreens and tinted moisturizers.
Benefits
- Provides broad-spectrum UV protection without chemical absorption
- Non-irritating option for sensitive skin and those prone to chemical sunscreen reactions
- Creates a brightening or mattifying effect on skin due to its white, reflective nature
Potential concerns
- Can leave a visible white cast on deeper skin tones
- May feel heavy or chalky if formulated poorly
- Nano-sized particles raise theoretical concerns, though topical use on intact skin is considered safe by major regulatory bodies
Science: Titanium dioxide is widely regarded as safe by the FDA, EU, and other regulators for use in cosmetics and sunscreens. Extensive safety data supports its use as a physical UV blocker; concerns about nano-particle inhalation apply primarily to manufacturing or inhaled exposure, not topical application on skin.
