It is all attributed to the photoinitiators that added into the gels. The photoinitiators react when exposed to various wavelengths of UV light. Most photoinitiators react upon exposure to 340-410nm of lights. Therefore, nail lamps emits lights in 340-410 can get the nail polishes cured and get them dry.

If you are exposed to ultraviolet light for four to eight minutes every two weeks when you have a gel manicure, that can add up to significant exposure.
