The cuticle is a thin layer of skin located at the base of the nail. It serves as a protective barrier, preventing bacteria and other harmful substances from entering the area where the nail grows. Proper care of the cuticle is important for maintaining healthy nails and preventing infections. In addition to its protective function, the cuticle also plays a role in nail growth. As new nail cells are produced, they push the older cells forward, forming the visible nail. Regular moisturizing and gentle pushing back of the cuticle can help keep it healthy, contributing to the overall appearance of the nails.
