A nail buffer is a small tool used to smooth and shine the surface of nails. It typically consists of a block or pad made of soft materials, often with different grits on each side. By gently rubbing the buffer against the nail, you can remove ridges and imperfections, resulting in a polished look without the need for nail polish. Using a nail buffer can enhance the natural shine of your nails and promote healthier nail growth. Regular buffing can also help improve blood circulation in the nail bed, contributing to overall nail health. Many people incorporate nail buffers into their manicure routines for a professional finish.
