How does Titanium Dioxide function as a sunscreen?

Titanium Dioxide functions as a sunscreen primarily by reflecting UV rays off of the skin. This physical or mineral sunscreen ingredient creates a barrier on the skin's surface that effectively scatters and reflects harmful ultraviolet radiation, protecting the skin from sun damage. Unlike chemical sunscreens that may absorb UV rays and convert them into heat, Titanium Dioxide remains on the skin and provides a reflective layer, making it particularly effective in preventing sunburn and long-term skin damage.

Additionally, Titanium Dioxide is known for its stability and broad-spectrum protection, covering both UVA and UVB rays. Its physical properties make it suitable for sensitive skin types, offering protection without the potential for irritation that some chemical sunscreens cause. This innate ability to act as a shield against UV radiation is what solidifies its role as an important ingredient in sun protection products.
