The primary purpose of using a top coat on nails is to enhance the durability of the nail polish. A top coat acts as a protective layer that seals in the color and provides a glossy finish, which not only improves the overall appearance of the nails but also helps to prevent chipping and fading. By adding this extra layer, it increases the longevity of the manicure, allowing the color to last longer and remain vivid.

In addition, a good top coat can also help to protect against the wear and tear that nails experience in everyday activities. It may contain ingredients that provide additional benefits, such as UV protection or quick-drying properties, further ensuring that the manicure remains intact for a longer duration.

While a base for nail art is useful, it does not fulfill the primary function of enhancing durability. Similarly, changing the color of the nails is not related to the role of a top coat, as it is intended to preserve the existing nail color. Removing excess polish is a different process altogether and does not pertain to the use of a top coat.
