What type of light is used to cure gel polishes?

The use of UV or LED light to cure gel polishes is accurate because gel polishes contain photoinitiators that react to these specific types of light. When exposed to UV or LED light, these photoinitiators initiate a chemical reaction that causes the gel to harden or "cure." This process is essential for ensuring that the polish adheres correctly to the nail and achieves the desired glossy finish.

UV lamps traditionally emit ultraviolet light, while LED lamps can cure gel products faster and are becoming more popular due to their efficiency and effectiveness. The wavelengths emitted by these lights are specifically designed to activate the compounds within gel polishes, making the curing process quick and reliable.

Other options, like incandescent light, fluorescent light, and natural sunlight, do not provide the appropriate wavelengths necessary to cure gel products effectively. Incandescent light lacks the ultraviolet spectrum, fluorescent light does not emit the correct type of light waves tailored for curing gel, and while natural sunlight has some UV components, it's inconsistent and not a controlled method for curing gel polishes.
