For best results, your nail polish needs a base coat and a top coat. The top coat prevents the colour chipping by sealing the colour coat. This gives you an optimal colour result that lasts longer. The base coat helps prevent discolouration of the nail itself. If you want to change the nail polish colour, this is easier and faster.
