What is the main effect of using a high-quality base coat before nail polish application?

Using a high-quality base coat before nail polish application serves the primary purpose of creating a protective barrier between the natural nail and the polish. This barrier is essential because it helps prevent staining or damage to the nail plate caused by the pigments in certain polishes. Additionally, it promotes better adhesion of the polish, which can lead to a longer-lasting manicure. The formulation of high-quality base coats often includes nutrients and conditioners that can also contribute to the health of the nails beneath the polish.

While other options such as enhancing colors and making removal easier may be secondary benefits of using a base coat, the main focus remains on providing that essential protective barrier. This not only helps in maintaining the integrity of the nails but also ensures that the polish adheres smoothly, which is key for achieving a professional-looking finish.
