What is the purpose of a base coat in nail care?

The purpose of a base coat in nail care is to protect the natural nail and enhance the adhesion of nail polish. By applying a base coat, you create a smooth surface that helps the color polish adhere better, thus reducing chipping and promoting longer wear. The base coat also serves as a barrier between the nail polish and the natural nail, helping to prevent discoloration or staining that can occur from the pigments in colored polishes. This protective layer ensures that the nails remain healthy while allowing for a more even application of the color polish.

While coloring the nails, removing stains, or creating designs on them are important aspects of nail care, they are not the primary functions of a base coat. The base coat's main role is specifically geared towards protection and adhesion, making it an essential step in any manicure process.
