What is the main benefit of using a base coat in nail application?

Using a base coat in nail application serves a crucial role primarily in protecting the natural nail and enhancing the adhesion of polish. The base coat creates a smooth surface that helps prevent staining from colored nail polishes and forms a barrier between the natural nail and the nail enamel, which can be particularly important for preserving nail health. This protective layer minimizes the risk of chipping and improves the longevity of the manicure by allowing the polish to adhere better, reducing the likelihood of peeling or lifting.

Additionally, the base coat prepares the nail surface for color application, ensuring a more even finish and allowing for better overall results. It is specifically formulated to bond with both the natural nail and the nail polish, enhancing wear time compared to applying polish directly onto the nail.
