The best time to apply nail polish is when they are completely dry

If you apply nail polish while your nails are wet, or right before they will become wet, they will be prone to chipping. Start off by filing your nails in the desired shape. Buffing them also helps to smooth the nail base and makes it easier to apply nail polish. Prepare your work area and then wash your hands thoroughly. Pat dry, then apply a small amount of water and nail polish remover to a cotton ball and swab your nails to remove any oils for better adhesion. You could also try facial toner which isnt quite as drying to the skin.
