Which type of nail product requires the use of a UV light?

Gels are a type of nail product that require the use of UV light to cure and harden the product on the nail. When applying gel nail products, the gel is applied to the natural nail or a nail extension, and then exposed to UV or LED light to initiate the curing process. During this process, the chemical composition of the gel changes, resulting in a durable and shiny finish that adheres well to the natural nail.

On the other hand, acrylics and wraps do not require a UV light for curing; acrylics harden through a chemical reaction when the monomer and polymer are mixed, and wraps typically rely on bonding agents and do not require light exposure. Dip powders also rely on a different technique involving a bonding agent and a sealant, rather than UV light for curing. Thus, gel nail products stand out as the sole category that necessitates UV light to achieve the desired results.
