What is the purpose of a nail buffer?

A nail buffer is specifically designed to polish the nail surface and enhance its shine. The buffer typically consists of several sides with varying grits, allowing the technician to smooth out any ridges and imperfections on the nail plate. By using the buffer, the natural oils of the nail are brought to the surface, resulting in a glossy finish without the need for additional products. This process not only improves the aesthetic appearance of the nails but also promotes overall nail health by stimulating circulation in the nail bed.

Other options, while related to nail care, do not accurately represent the primary function of a nail buffer. For instance, reshaping the nail is typically done with a file, not a buffer. Removing nail polish requires an entirely different approach, usually involving a remover, while strengthening the nail is more focused on treatments and products designed specifically for building nail integrity. Thus, option B captures the essence of what a nail buffer is primarily used for in a manicure.
