-The most obvious must be that it will smooth out ridges on the surface of your nails, which will indirectly make your nail polish adhere better.

-And, as an alternative to clear nail polish, it will give you smooth and shiny nails without worrying about nail polish that will start chipping.

-It will also help you get rid of dry and dead surface cells on your nails.

-Buffing stimulates blood circulation to the nail bed, which encourages the nails to grow faster and contribute to the general health of the nails.

• You cannot use (most) buffers to shape your nail, as their grits are too fine. Use an emery board or nail file instead.
• It won’t magically make nail surface stains vanish. Very superficial stains could be buffed away, but since too much buffing can damage your nail, this is not the ideal solution for fixing stained nails.
• Buffing cannot remove or soften nail cuticles. Cuticles are the fleshy part that extends from the nail bed on your nails. You can use a cuticle cream to soften and push it back.

• You have thin and “bendy” nails.
• You have brittle nails.
• Your nails are chipped. Buffing should only be done after you have shaped your nails neatly with your nail clipper and nail file.

• Make sure your nails are dry and clean before starting. Wet nails are more prone to damage.
• Remember to push your cuticles back before you buff your fingernails.
• Do not buff your nails more than once a month. Buffing too often will thin and weaken your nails.
• Never use an emery board or regular nail file to buff your nails. Always use a super-fine-grit nail buffer to lightly smooth ridges. You should just barely be able to make out the grains on the buffer when you touch it.
• Use gentle, light uni-directional strokes and never use back and forth strokes. Never use a sawing motion. It will do more harm than good.
• Stop immediately if you experience any burning sensation, redness or if your nails become hot. This means you are using too vigorous strokes and might be harming your nails.
