Editor's Pick: If your nails tend to peel or split easily, this one is worth a try. It forms a hard protective layer on the nail surface, so everyday activities like typing or opening bottle caps are less likely to scratch your nails. The clear formula works well on its own or as a base coat without affecting the color of your polish. The brush is a good size, and a thin coat dries quickly—with consistent use, your nail bed will feel noticeably firmer.
