Pure titanium dioxide is a fine, white powder that provides a bright, white pigment. It is used in some cosmetics to aid in hiding blemishes and brightening the skin. Titanium dioxide works as a UV filtering ingredient in sunscreen – it helps protect a person’s skin by blocking absorption of the sun’s ultraviolet light that can cause sunburn and is also linked to skin cancer. This powder allows for the use of thinner coatings of make-up material for the same desired effect.
Titanium dioxide becomes transparent to visible light while serving as an efficient UV light absorber.
