Titanium Dioxide is a naturally occurring mineral that acts as a physical sunscreen, reflecting and scattering UV radiation. It is also used as a white pigment in cosmetics, providing opacity and brightness. In its nano form, it can offer a more transparent finish on the skin.

Yes, Titanium Dioxide is considered safe and effective as a sunscreen ingredient by regulatory bodies worldwide. It primarily stays on the skin's surface, providing a physical barrier against UV rays.
What is the difference between nano and non-nano Titanium Dioxide?
Nano Titanium Dioxide has smaller particles, which can reduce the white cast often associated with mineral sunscreens, making them more cosmetically elegant. Non-nano particles are larger and tend to leave a more visible white layer on the skin.
