Which product would you use to prevent polish from staining the nail bed?

The use of a base coat is essential for preventing polish from staining the nail bed. A base coat acts as a protective barrier between the natural nail and the color polish applied on top. It helps to seal the nail surface, thereby reducing the chances of pigments from the nail polish penetrating the nail plate and causing discoloration. This is particularly important when using darker or more vibrant colors, which are more likely to stain.

On the other hand, a top coat is designed to provide a shiny finish and extend the wear of the manicure, but it does not serve the same protective function against staining. Cuticle oil is used to nourish the cuticles and surrounding skin, and nail polish remover is meant for removing polish rather than preventing staining. Therefore, using a base coat is the best practice for maintaining the health and appearance of the natural nail bed.
