Artificial nails, also known as fake nails, false nails, fashion nails, nail enhancements, or nail extensions, are coverings placed over fingernails as fashion accessories. Some artificial nails attempt to mimic the appearance of real fingernails as closely as possible, while other designs may deliberately stray in appearance from real fingernails. Artificial nails are made from a wide variety of materials.
Nail polish is a lacquer applied to human finger or toe nails to decorate and protect the nail plate. Today's nail polish is a refined version similar to the paint on vehicles. However, its formula has been revised repeatedly to prevent the cracking or flaking that occurs with the natural movement of the nail.
