How is gel polish typically applied?

Gel polish application involves applying the polish in thin layers, which allows it to cure properly under a UV or LED lamp. This process is crucial because the curing of each layer transforms the gel from a liquid state into a durable, solid finish that provides long-lasting wear without chipping. The thin layers also contribute to an even application and help prevent issues such as bubbling or peeling that can occur if applied too thickly.

In contrast, other methods of application mentioned in the choices either do not accurately reflect the gel polish process or result in inferior outcomes. For example, applying gel polish in thick layers could lead to improper curing and a subpar finish. Using a fan for a single layer would not achieve the essential curing process and would not create a lasting bond on the nail. Soaking nails in a solution is a method used for other types of nail services, such as removing certain types of polish or products, and is not applicable for gel application.
