The most annoying thing is when the tips of your nail polish is all chipped off....

Dip a tissue or cotton ball in nail polish remover

Voila! Now when applying nail polish to fix chips the ridges will be minimal.

Now just paint the part of the nail without polish....

Slight ridges may be noticeable...

...but with a quick clear coat the problem should be fixed!
