How is an ultraviolet (UV) lamp used in gel manicures?

An ultraviolet (UV) lamp is specifically designed to cure and harden gel polish during a gel manicure. The gel polish contains photoinitiators that react to UV light, leading to a chemical process that hardens the gel. This curing process is essential because it strengthens the gel product and ensures a long-lasting finish that is durable and chip-resistant.

Using a UV lamp also enables the gel to adhere properly to the natural nail, which is crucial for a successful and lasting manicure. The proper use of the lamp is vital in achieving the desired results, as the gel must be exposed to the UV light for a specific amount of time for the curing process to be effective. This step distinguishes gel manicures from traditional nail polish, which dries through evaporation rather than a curing reaction.
