1. Make sure there are no fans or sources of moving air in the room. Too much movement can induce bubbling

2. Despite what you might have learned, don't shake your bottles before use. This gets air bubbles in the polish; try rolling the bottles between your palms instead.

3. If you have the time, stick your nail polish in the refrigerator for ten minutes before using it.

4. Don't put any lotion or oils on your nails before polishing them, the oil can react with the polish and cause bubbles.

5. To make sure there's no oil or other product left on your nails, put some white vinegar on a cotton ball and wipe your nails with it. The acidic vinegar will get rid of any residue.
