Using a base coat before applying nail polish is primarily beneficial for preventing nail polish from chipping. The base coat acts as a protective layer that adheres to the natural nail and provides a smooth surface for the colored polish to grip onto. This adhesion is crucial because it helps maintain the integrity of the nail polish, reducing the likelihood of it cracking or peeling. Furthermore, the base coat can help to absorb some of the impacts and stresses that nails face in daily activities, extending the longevity of the manicure.

While other options, such as creating a glossy finish or enhancing nail fortitude, are attributes associated with certain types of nail products, they are not the primary purpose of a base coat. The glossy finish is typically achieved with top coats, and nail fortitude or strength is generally addressed by specific strengthening treatments designed for that purpose. Therefore, the main advantage of utilizing a base coat lies in its essential role in securing the nail polish to the nail bed and minimizing chipping.
