What product is often used to seal nail enhancements?

The use of a top coat is essential in nail enhancements as it serves several important functions. A top coat provides a protective layer that seals the surface of the nail enhancement, helping to prevent chipping and scratching. It enhances the shine and overall appearance of the nails, making them look more polished and finished. Additionally, a top coat can offer a layer of UV protection, helping to prevent discoloration from sun exposure or artificial lights.

While a base coat is crucial for preparing the natural nail and ensuring that enhancements adhere properly, its primary function is not to seal but to create a suitable foundation. Cuticle oil is often used to nourish the skin around the nails and maintain health but does not serve the purpose of sealing enhancements. Nail hardener is designed to strengthen nails but does not provide the sealing and protective characteristics that a top coat offers. Therefore, the top coat is the product that directly fulfills the need to seal nail enhancements.
