Older nail lamps on the market can cause skin damage, dryness or aging, and even cancer due to prolonged exposure to ultraviolet radiation. And the service life of the lamp beads is not long, requiring frequent replacement, and the distribution of the lamp beads is not scientific, resulting in uneven irradiation and different degrees of curing, which affects the nail art effect.

Now, we use ultraviolet or LED light sources. They can accelerate the reaction of photoinitiator in nail gel through light irradiation of specific wavelength, so as to achieve rapid curing. UV lamps have high power and fast curing speed, while LED lamps are relatively energy-saving and use single wavelength light, which causes less damage to the skin.
