What is the primary purpose of cuticle tissue?

The primary purpose of cuticle tissue is to protect the nail bed, which is the skin underneath the nail plate. The cuticle acts as a barrier, preventing bacteria, fungi, and other harmful elements from entering the sensitive areas of the nail matrix and the nail bed. By sealing off the area where the nail originates, the cuticle helps maintain the health of both the nail and the underlying skin, preventing infections and promoting overall nail integrity.

While nourishment and support for nail growth are important functions associated with healthy nails, these roles are more directly linked to the nail matrix and the surrounding structures rather than the cuticle itself. The cuticle does not provide nourishment, nor does it directly enhance the appearance of the nails; rather, its main function is protective.
