What is the best way to ensure a smooth polish application?

Applying polish in thin, even layers is the best technique to achieve a smooth finish. This method allows for better control over the application, preventing streaks and achieving a more uniform appearance. Thin layers dry more quickly and reduce the likelihood of bubbles or imperfections forming in the polish. Applying polish evenly across the nail surface ensures that the color is distributed uniformly, which is essential for a professional-looking manicure.

Using a base coat only does not contribute to the smoothness of the polish application itself; rather, it's intended to protect the nail and enhance the adhesion of the polish. Applying in thin, uneven layers can lead to patches and inconsistencies, resulting in a less polished look. Finishing with a matte top coat may alter the desired finish of the nail and does not enhance the overall smooth application of the color polish. Therefore, focusing on thin, even layers is the most effective approach for achieving a polished and smooth appearance.
