The purpose of a top coat is to seal the nail polish and add shine. This protective layer is applied over colored nail polish to enhance its durability and longevity, preventing chipping and extending the overall wear-time of the manicure. Additionally, a top coat provides a glossy finish that enhances the appearance of the color underneath, making nails look polished and well-groomed.

While quick-drying products are available, they are typically categorized as quick-dry top coats, which serve a specific function separate from the traditional purpose of a top coat. Changing nail color is not a role of a top coat; rather, it is intended to enhance and protect the existing polish. Strengthening the natural nail is a purpose associated with specific nail treatments or base coats but not with a top coat, which focuses primarily on polish protection and shine.
