What is the purpose of using a nail buffer?

Using a nail buffer serves the primary purpose of improving the appearance of the nail surface. Buffing works by smoothing out ridges and imperfections on the nail plate, creating a polished and glossy finish. This process enhances the overall look of the nails, making them appear healthier and more well-groomed.

When buffing, the nail's outer layer is gently polished, which helps reflect light better, thus giving the nails a shiny and attractive look. This is particularly beneficial for those who prefer natural nails without polish, as a good buff can elevate the nails' aesthetic appeal without additional products.

Other options do not accurately reflect the primary function of a nail buffer. For instance, removing nail polish is the role of a nail polish remover rather than a buffer. Similarly, applying a protective coating typically involves the use of topcoat products rather than a buffer. Cutting away dead skin pertains to nail care techniques involving cuticle removal, which is unrelated to the smoothing effect achieved through buffing the nail surface.
