What is the recommended step after removing the inhibition layer during a two colour UV gel application?

In the context of a two-colour UV gel application, after removing the inhibition layer, the correct step to take is to check the nail for contours. This step is crucial because it ensures that the application has a smooth and even surface, which is essential for both the aesthetic appearance and the durability of the gel. By examining the contours of the nail, the technician can identify any areas that may require additional filing or smoothing, ensuring that the final look is polished and professional.

Applying a base coat would typically be done at the beginning of the process, and applying a top coat occurs at the end of the application once everything is in place. Cleaning the workspace is important for maintaining a tidy environment, but it is not directly related to the nail's preparation after the inhibition layer is removed. Therefore, assessing the contours of the nail is the most logical and necessary step at that point in the application process.
