What is the purpose of a nail buffer?

The primary purpose of a nail buffer is to smooth and shine the surface of the nail. Buffers are designed with different grits that gradually refine the surface of the nails, creating a glossy finish. This process enhances the natural appearance of the nails, making them look healthier and more polished without the need for nail polish. Regular use of a nail buffer can help to improve the texture of the nail surface, remove minor imperfections, and promote a more finished look, particularly in natural nails.

The other options focus on different nail care functions: trimming nails is achieved through clippers or scissors, cuticle removal involves different tools specifically designed for that area, and applying nail polish requires brushes or applicators rather than a buffer.
