Nail tops are top coats applied over colored polish or gel polish. They protect the manicure from chips and scratches. Tops add gloss or a matte finish. They increase the durability of the coating. Some tops provide decorative effects, such as shimmer or “cat eye.” There are different types of tops. Glossy tops give a mirror-like shine. Matte tops make the surface velvety. Tops with effects can contain glitter, powder, or a colored tint.
