An inorganic compound, titanium dioxide is used in a wide range of products in the cosmetic industry, including mineral makeup and powders, and sunscreen products. Titanium dioxide functions as a sunscreen by deflecting and diffusing light, making it an effective UV ray blocker, often referred to as a physical sunscreen ingredient.
Titanium dioxide deflects UV rays from the skin’s surface, preventing them from penetrating the surface layer of the skin and causing damage in the layers underneath. When used on its own, titanium dioxide protects against both UVA and UVB rays, making it an effective choice for those looking for a broad spectrum, physical sunscreen.
Titanium dioxide is also widely used in mineral makeups and powders due to its ability to diffuse light and provide an even, smooth appearance to the skin’s surface.
