Hand lotion is one of the main reasons polish peels off, as it leaves a film on your nails. Prior to applying a base coat (a must-do for nail polish longevity), take a cotton swab and dip it in nail polish remover. Then go over each nail to remove any residue from hand and nail care prep products. After applying a base coat, allow 2-3 minutes of dry time before adding two coats of polish. Allow the same amount of dry time between each coat, followed by a top coat.
