What is the purpose of base coat nail polish?

The purpose of base coat nail polish is primarily to provide a smooth surface for nail polish application and to help prevent staining of the natural nail. A base coat acts as an intermediary layer between the natural nail and the colored polish, thereby creating a better adhesion surface for the polish. This promotes a more even application of color while enhancing the longevity of the manicure.

Additionally, base coats often contain ingredients that can protect the nail from discoloration, particularly from darker colored polishes that may stain the nail plate. This preventive layer is crucial for maintaining the health and appearance of the natural nail.

Other nail polish products have different functions; for instance, top coats add shine and create a protective layer over the color polish, while colored polishes serve to enhance the aesthetic with vibrant hues. In contrast, a base coat focuses on preparing the nail for polish and ensuring both protection and adhesion.
