Which process is essential for nail preparation before applying polish?

Buffing the nails is an essential process for nail preparation before applying polish. This technique helps to create a smooth surface on the nails, which allows for better adherence of the polish. A well-buffed nail surface reflects light more evenly, enhancing the overall appearance of the polish applied. Additionally, buffing can help remove ridges and minor imperfections, contributing to a polished finish. It ensures that the foundation for the color application is optimal, reducing the likelihood of chipping or peeling once the polish is applied.

While options such as moisturizing the hands and soaking the nails in water may contribute to overall hand and nail care, they do not specifically prepare the nail surface for polish application in the same direct way that buffing does. Painting with a clear coat is typically a step taken after the polish has been applied, making it a subsequent, rather than preparatory, phase in the manicure process. Thus, buffing stands out as the key step necessary for ensuring the nail surface is ready for polish.
