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 nail bed. The cuticle is made up of dead skin cells and is an important part of nail health. In addition to its protective function, the cuticle also helps to keep the nail hydrated. Regular care, such as moisturizing and gentle pushing back of the cuticle, can promote healthy nail growth. Neglecting the cuticle can lead to issues like hangnails or infections, affecting the overall appearance of the nails.
