UVBFilter

UVBFilter refers to a substance or material that absorbs or reflects ultraviolet B (UVB) radiation. UVB rays are a component of the sun's ultraviolet light spectrum and are known for their role in causing sunburn and contributing to skin cancer. Many sunscreens contain UVB filters as their active ingredients, which work by either absorbing UVB rays and converting them into less harmful heat, or by physically reflecting them away from the skin. Common examples of UVB filtering ingredients include zinc oxide, titanium dioxide, avobenzone, and octinoxate. The effectiveness of a UVB filter is measured by its Sun Protection Factor (SPF), which indicates how much longer skin protected by the substance can be exposed to UVB radiation before it starts to burn compared to unprotected skin. Beyond personal care products, UVB filters are also incorporated into various materials to prevent degradation from UV exposure, such as in paints, plastics, and textiles. These filters play a crucial role in protecting both human health and the longevity of materials from the damaging effects of UVB radiation.
