What type of light does a UV lamp emit in gel nail curing?

A UV lamp emits ultraviolet light, which is essential for curing gel nails. The gel nail products contain photoinitiators that react when exposed to UV light, triggering a chemical process that hardens the gel and allows it to bond securely to the nail. This process is crucial for ensuring that the gel nails last without chipping or lifting.

Visible light, while important in various aspects of the salon environment, does not provide the necessary wavelength to cure gel products. Infrared light, primarily associated with heat rather than the curing process, does not activate the photoinitiators in gel nail formulations. Natural light lacks the specific ultraviolet wavelength required to effectively cure gel polymers. Therefore, ultraviolet light is the only type of light that can achieve the desired results in gel nail applications.
