What is the function of nail cuticles?

The function of nail cuticles is primarily to protect the area between the skin and the nail plate. Cuticles serve as a barrier that helps prevent bacteria and other pathogens from entering the nail bed and causing infections. They also play a role in keeping moisture in, which is essential for maintaining healthy nails. This protective layer helps to ensure that the area around the nail remains healthy, newly forming cells have the necessary environment for proper growth, and the risk of injury is minimized.

While other aspects of nail health may be influenced by factors such as diet or nail care practices, the primary role of cuticles is to provide that essential protection.
