What is the inhibition layer when applying gel polish?

The inhibition layer refers to the sticky residue that remains on the surface of the gel polish after it has been cured under a UV or LED light. This layer is a natural byproduct of the curing process, where the photoinitiators in the gel react with light to start the polymerization, but do not completely cure, leaving a tacky surface.

This sticky layer is important because it helps the next layer of product adhere properly, whether that's additional gel polish, top coat, or any other enhancements. Without the inhibition layer, the subsequent product may not bond effectively, leading to peeling or chipping.

It is crucial for nail technicians to understand and manage the inhibition layer correctly, as it ensures a strong, long-lasting finish for their clients' nails.
