What is essential when preparing nails for UV gel application?

The correct choice is to use a dehydrator on the nail plate during the preparation for UV gel application. This step is crucial because it helps eliminate any moisture and oils on the surface of the nails, ensuring better adhesion of the gel. A dehydrator is specifically formulated to prepare the nail by balancing the natural moisture content, which prevents lifting and enhances the longevity of the gel manicure.

Using a dehydrator promotes a clean and dry nail surface, which is optimal for the gel to bond effectively. This preparation step minimizes the risk of problems such as chipping or lifting that could occur if moisture or oils are present.

While completely drying the nails before application is important, it is typically part of the process but not as specifically vital as applying a dehydrator. Leaving moisture on the nail is not advisable, as it can interfere with the adhesion process of the gel. Applying a thick base coat is often unnecessary for a proper gel application; a thin, even base coat usually works best to ensure the gel adheres correctly and provides a smooth surface for the application of subsequent layers.
