Titanium Dioxide

Titanium dioxide is a multi-functional ingredient that has earned a reputation as the "gold standard" in products ranging from sunscreens to foundations.

Titanium dioxide in skin care is valued for its effective sun protection and its ability to even out skin tone. However, the long-term safety of titanium dioxide (especially in nanoparticle form) is still being actively studied.

How to use it

Titanium dioxide is used as a mineral UV filter. In particular, titanium dioxide on skin works as a physical barrier that reflects and scatters UV rays, protecting skin from both UVB and UVA radiation. It's effective and carries a low risk of irritation, which makes it a popular choice in sunscreens for sensitive skin.

As a white powder, it also serves as a high-quality white pigment (listed as CI 77891 in ingredient lists). It's added to foundations, powders, lipsticks, and even toothpaste to give them opacity, brightness, and rich color.

Suitable for

Any skin type.

FAQ

1. Is titanium dioxide safe in makeup?

Yes, titanium dioxide on skin is considered safe when applied through creams, foundations, powders, and more. Manufacturers often highlight the use of non-nano particles to show that they don't penetrate deep into the skin.

2. Is titanium dioxide safe for pregnancy?

Yes, using titanium dioxide in topical products is considered safe during pregnancy.

3. Is titanium dioxide a mineral or chemical UV filter?

Titanium dioxide falls into the category of physical (or mineral) sunscreen filters. It works by reflecting, scattering, and blocking UV rays, rather than absorbing them like chemical filters do.
