What is the main purpose of a top coat in nail application?

The main purpose of a top coat in nail application is to prevent colored enamel from breaking. A top coat serves as a protective layer over the colored polish, creating a barrier that helps to resist chipping, peeling, and wear. This protective function is essential because the colored enamel alone can be more prone to damage from daily activities, such as typing or washing dishes. By applying a top coat, you not only extend the longevity of the nail polish but also keep it looking vibrant and fresh for a more extended period.

While there are other functions associated with nail products, such as enhancing color, speeding up drying time, or preparing the nail surface by removing cuticles, these are not the primary role of a top coat. The core objective remains focused on protection, ensuring that the beautiful color underneath remains intact and aesthetically pleasing for as long as possible.
