What is the primary purpose of using a base coat?

The primary purpose of using a base coat is to protect the natural nail and assist with the adherence of the color polish. A base coat creates a barrier between the natural nail and the colored polish, preventing potential staining from pigments present in the color. It also enhances the longevity of the manicure by providing a surface that allows the color polish to adhere better, reducing chipping and peeling. This protective layer helps maintain the health of the natural nails during the wear of colored polishes. In addition to its protective qualities, a base coat can also smooth out the surface of the nail, which may further assist with even color application.
