At present, nails are mostly used in phototherapy, and the use of light -efficient cohesion in nail polish glue will be performed under the principle of curing reactions under ultraviolet rays. The lights we take when nails are actually ultraviolet lamps. The wavelength of UV lamps used in nail lights is generally 320-400nm. It belongs to the range of long waves of ultraviolet rays. It will not cause particularly serious damage to the skin, but it will cause the skin to be dark and aging.

LED phototherapy lamps have better protective effects on skin and eyes than UV and other lights! Because the LED light is longer than the wavelength of the UV light, it can be dried in about 30 seconds by dried a nail polish LED light, while the ordinary UV light takes 3 minutes to dry. For nails with thin nail art, the pain of LED lights will slow more than UV lights. UV lights can dry all brands of phototherapy glue and nail polish gum, but LED can take all the nail polish gels, but it may not be able to dry the light gum ~ So in terms of omnipotentiality, the UV light is slightly better than Intersection There are also light machines combined with UV lights and LED lights. If there is a need for nail polish and phototherapy gels at the same time, you can consider it.
