Which polish is applied over regular polish to prevent chipping?

The application of a topcoat over regular nail polish serves several essential purposes, with the primary function being to prevent chipping. A topcoat forms a protective layer on top of the colored polish, enhancing the durability of the manicure. It creates a barrier that helps to shield the color from everyday wear and tear, impacts, and environmental factors, which contributes to a longer-lasting finish.

In addition to its protective qualities, a topcoat can also enhance the overall appearance of the nails by adding shine or a matte finish, depending on the type of topcoat used. This additional layer not only helps to maintain the polish's integrity but can also enhance the color and visually enrich the manicure.

While a base coat is important for providing a smooth surface for polish application and protecting the natural nail, it does not serve the same function as a topcoat in terms of preventing chipping after the color has been applied. Gel polish is a type of polish that offers a longer-lasting and more durable option on its own but is not a product meant to be layered over regular polish for the purpose of preventing chips. A matte finish, while it alters the appearance of the nails, does not provide the same protective qualities that a topcoat does.
