Titanium Dioxide In Skin Care-Is Titanium Dioxide A Broad Spectrum Sunscreen

Titanium dioxide is indeed considered a broad-spectrum sunscreen. Sunscreens are labeled as “broad-spectrum” when they provide protection against both ultraviolet A (UVA) and ultraviolet B (UVB) rays. Titanium dioxide is a physical, or inorganic, sunscreen ingredient that works by reflecting and scattering UV radiation away from the skin.

UVB rays are primarily responsible for causing sunburn, while UVA rays penetrate deeper into the skin and are associated with premature aging and skin cancer. Titanium dioxide is effective at reflecting UVB rays, and it also provides some protection against UVA rays, although it’s not as effective against UVA as zinc oxide, another common broad-spectrum sunscreen ingredient.

The broad-spectrum protection of titanium dioxide can vary depending on its particle size and formulation within the sunscreen product. For optimal broad-spectrum protection, titanium dioxide is often combined with other sunscreen agents.
