What is the primary purpose of a top coat in nail care?

The primary purpose of a top coat in nail care is to protect the polish and enhance its durability and shine. When applied over colored nail polish, a top coat creates a hard, protective layer that helps to prevent chipping, scratching, and fading. This additional layer not only preserves the integrity of the underlying color but also typically includes properties that enhance the overall appearance, giving the nails a glossy finish. The shine provided by the top coat also contributes to the overall aesthetic of the manicure, making the colors appear more vibrant and polished.

While a top coat can help slightly with drying and may assist in a quicker drying time compared to polish alone, its main function remains focused on protection and enhancement rather than speed. It does not typically add color; that function is reserved for the base colors applied beneath it. Additionally, while top coats can provide a nice base for nail art, their primary responsibility is not to serve that purpose but rather to finish and protect the nail design.
