* Smoothing Ridges and Imperfections: Buffers are often used to smooth out any ridges, bumps, or imperfections on the surface of the nail, creating a more even canvas for polish or for a natural, polished look.
* Creating Shine: Buffing the nails with the appropriate grit levels can bring out a natural shine. It works by gently smoothing the nail surface and creating a glossy appearance without the need for polish.
* Stimulating Circulation: The act of buffing can stimulate blood flow to the nail bed, which is believed to promote healthier nail growth.
* Preparing for Polish: By creating a smooth surface, buffing helps nail polish adhere better and last longer.
Different sides or grits of a buffer are used for different stages of the process, from filing down ridges to achieving a high-shine finish.
