What does the cuticle do?

The cuticle plays a vital protective role for the nail structure, particularly in safeguarding the underlying matrix, which is the area responsible for nail growth. The cuticle acts as a barrier between the nail plate and the external environment, preventing bacteria and other pathogens from entering the area that could lead to infection or damage to the matrix.

While the cuticle does indeed support the structure of the nail and is part of the skin surrounding it, its primary function is to ensure the health and integrity of the nail matrix beneath. This protective aspect is crucial for maintaining healthy nail growth and preventing potential complications.
