What is UPF?
**Both SPF (Sun Protection Factor) and UPF (Ultraviolet Protection Factor) are standards used to measure sunburn protection. SPF, the standard used to measure the effectiveness of sunscreens, has been around for many years. The UPF system is relatively new and was created specially for sun protective fabrics. At first, American sun protective fabrics were rated using the SPF standard until the FTC finalized the UPF standard we have today. Use of the UPF standard is voluntary so some sun protective fabric manufactures still use the SPF system.
Which is better SPF or UPF?
When it came to UVA rays (the type of radiation that is also linked to skin cancer, but more commonly associated with wrinkles and aging), the UPF fabrics offered rates of protection at around 96% to 98%. By contrast, the sunscreens performed at considerably lower rates of roughly 54% (SPF 30) to 82% (SPF 50).
