What is a benefit of smoothing the nail surface using a buffer?

Smoothing the nail surface using a buffer primarily enhances the shine of the nails. Buffing removes any imperfections on the nail plate, resulting in a smoother surface that reflects light more effectively. This process not only improves the appearance of the nails but can also create a healthier look, making them visually appealing without the need for nail polish.

While hardness and prevention of breakage are important considerations in nail care, these effects are not the direct results of buffing. Additionally, buffing does not lighten the natural nail color; its main intention is to refine the smoothness and shine of the nail surface. Thus, enhancing shine through buffing is a key benefit that directly contributes to a polished and well-groomed appearance.
