SPF stands for Sun Protective Factor, and usually relates to sunscreens, creams & cosmetics- it indicates how long it will take for UVB rays to turn our skin red when using sunscreen compared to how long it would take the skin to redden without the product. For example, a sunscreen with an SPF of 15 will delay the beginning of a sunburn in a person who would otherwise burn in 10 minutes to burn in 150 minutes. Dermatologists recommend a minimum SPF sunscreen of 15, and remember, apply enough and apply often!
UPF stands for Ultraviolet Protective Factor, and is related to clothing. It indicates how much UV radiation can penetrate the fabric, so the higher the UPF, the better. All of our products offer UPF50+ which is the highest available in the market protecting your skin from both- blocking 99% of the harmful UV Rays. Regular clothing has basically no protection- less that 6%. So there is a big difference between regular clothing and UV Couture Clothing.
UVA (long wave ultraviolet A) and UVB (short wave ultraviolet B) are responsible for conditions such as premature skin aging, eye damage, and skin cancers. They also suppress the immune system.
Ultimately, UVA rays cause aging, while UVB rays cause burning- we need protection from both. The reality is that no method is 100% effective. We recommend wearing UV Couture UPF50+ sun protective clothing along with an SPF 15 (or higher) to all other exposed areas of skin.
We hope this blog has helped you understand the difference between SPF and UPF- make sure to share this information to help others enjoy an incredibly fun & sun safe summer!
