Ultraviolet radiation causes skin aging but also can lead to deep and coarse wrinkles, rough skin, uneven skin tone, spots, skin thickening, relaxation, local excessive pigmentation or hyperbole and so on.UPF is short for Ultraviolet Protection Factor, which translates to UltravioletProtectionFactor.
UPF50+ means that 1/50 of the UV radiation can penetrate the fabric. The higher the UPF value, the better the protection effect. However, the highest UPF mark for textiles in the world standard is 50+, also known as UPF>50. Since UPF is greater than 50, the effect on the human body is completely negligible.
