What is the primary purpose of using a base coat in nail applications?

The primary purpose of using a base coat in nail applications is to extend the wear of polish. A base coat acts as a primer for the nails, providing a smooth surface for the nail polish to adhere to. This adhesion reduces the likelihood of chipping and peeling, allowing the polish to last longer and maintain its appearance. The base coat also helps to improve the overall finish of the nail application, ensuring that the color applied on top appears vibrant and even.

While other options suggest benefits of a base coat—such as protection for the nail bed or enhancing nail color—the key function that is widely recognized in the nail care industry is its role in prolonging the lifespan of nail polish. Therefore, using a base coat is essential for achieving a durable manicure that endures everyday wear and tear.
