Nail polish (also known as nail varnish in British English or nail enamel) is a lacquer that can be applied to the human fingernail or toenails to decorate and protect the nail plates. The formula has been revised repeatedly to enhance its decorative properties, to be safer for the consumer to use, and to suppress cracking or peeling. Nail polish consists of a mix of an organic polymer and several other components that give it colors and textures. Nail polishes come in all color shades and play a significant part in manicures and pedicures.
