Q titanium dioxide in lip balm
RoyYerkes
MonaWalter Release Time: July 5, 2024, 4:02 AM
Titanium dioxide is often used in lip balms as a physical sunscreen and pigment. As a non-toxic, inert substance, it helps protect the lips from the harmful effects of UV radiation, preventing sunburn and reducing the risk of skin cancer. Additionally, its white pigment property is useful in opaquely tinting or lightening the color of lip balms. However, the safety of nano-sized titanium dioxide particles has raised concerns, as they can be absorbed more easily by the skin. Most research indicates that conventional (non-nano) titanium dioxide remains on the surface of the skin and is considered safe for topical use. Consumers looking for more natural lip care alternatives or concerned about nano-particles might opt for products specifically labeled as non-nano or free from titanium dioxide.
