It’s important to wipe nails with a cloth before applying nail polish. Oils left on the nail will keep polish from sticking.
When applying nail polish, be sure to bring it over the front edge of the nail and slightly under the tip. This helps prevent chipping.
If the polish chips, it’s best to remove the paint from the nail and start over. If you don’t have time, dip your finger in nail polish remover and smooth over the chipped area and re-apply a topcoat.
The secret to keeping nails from smudging: dry time!
Surfaces will feel dry to the touch after 10 minutes, but don’t be fooled. It actually takes an entire hour for nails to completely dry.
