The term SKIN ABOVE A FINGERNAIL can be summarized as the CUTICLE. The CUTICLE is a thin layer of skin located at the base and sides of the fingernail. It serves to protect the nail bed from bacteria and other contaminants. It also helps to keep the nail plate firmly attached to the nail bed. The CUTICLE is composed of dead skin cells and is usually transparent. It is important to keep the CUTICLE healthy and moisturized in order to maintain healthy nails.
