4. Use a Nail Buffer Block

A nail buffer has a similar texture to sand paper with four sides. Each side has a different purpose for your nails but you should aim to use all of them to reap the benefits!

Rub it against your nails to get rid of any ridges and scratches while it smooths them over and turns them super shiny. This is great for the occasional use (when your nails need some tightening and polishing up) but don't over-use as it can damage your nails.
