Which type of light source is commonly used to cure light-cured gel nails?

The correct choice is that LED light sources are commonly used to cure light-cured gel nails. LED lamps emit specific wavelengths of light that are effective in activating the photoinitiators within the gel products, which initiates the curing process, resulting in a hard and durable finish. This method offers several advantages, including faster curing times and a reduced risk of heat generation compared to other light sources.

Halogen lights, while sometimes used in older systems, do not provide the specific wavelength needed for optimal curing of modern gel products. Incandescent lights generate heat but lack the necessary UV wavelength to effectively cure gel nails, making them unsuitable for this purpose. Similarly, fluorescent lights do not emit the precise wavelengths required for the gel curing process and are not commonly utilized for this application.

In summary, the use of LED lights is preferred and widely adopted in the nail industry due to their efficiency, effectiveness, and compatibility with light-cured gel formulations.
