Remove Old Polish
This first step isn't exactly rocket science, but it's amazing how many women leave polish on their nails, hoping it will eventually chip away. But no matter how much time goes by, there's always one stubborn patch that refuses to leave. Worse, if left over time, old polish can cause nail discoloration. So, be sure to remove any old polish before starting your pedicure.
At the drugstore, you'll see both acetone and non-acetone polish removers. Acetone is better for removing color but the ingredients can dry out your skin. Non-acetone polish remover is gentler because it was originally used for synthetic nails, but it won't remove your nail color as well as acetone. So what do you choose? Use an acetone polish remover, but go easy on the cuticle area, where the acetone can really dry out the skin.
