8. Buff and File Lightly
In between manis, use the proper tools to buff and file your nails into top coat-worthy ultra-shininess and smoothness. “Always file nails in one direction to prevent damage, chipping and cracking,” Elle recommends. 
These buffers do the job beautifully, especially on ridges and stains, sans stripping nails’ top surface layer; the files are professionals’ choice:
