【UPF 50+ Protection】MelodySusie Manicure Gloves are used when you do gel manicures to protect against the harmful and aging UV and LED rays that may leak from gel curing lamps (both UV and LED lamps may have UVA rays that may cause age spots, wrinkles and potential skin cancer). Our gloves are made with Certified UPF 50+ material, which effectively blocks over 99% of these rays. 【Comfortable Material】Our UV shield glove is made of soft LYCRA fabric with 85% Nylon 15% Spandex, comfortable and breathable which has moisture transfer technology that transports the heat and sweat to drier areas-away from the skin to the exterior of the gloves where it can evaporate more efficiently.
