What is the surface left on the nail after UV or LED gel has cured known as?

The surface left on the nail after UV or LED gel has cured is known as the inhibition layer. This layer is a result of the chemical reaction that occurs during the curing process, where the top layer of the gel remains slightly uncured due to the nature of the curing mechanism.

The inhibition layer is important because it provides a slightly sticky feel that helps with the adhesion of subsequent products, like top coats or nail art. This tacky surface indicates that the gel has cured properly underneath and is ready for additional layers.

In contrast, other layers, such as the finish layer, refer to a smooth, non-sticky surface that is typically achieved after applying a topcoat and curing again. The adhesive surface is more about how products bond to the nail, while the tacky layer may not always imply a bond-ready state; it serves a specific purpose in gel application. This understanding is crucial for nail technicians to ensure the best results and longevity of the gel manicure.
