What is the primary function of the nail cuticle?

The primary function of the nail cuticle is to prevent infection around the nail. The cuticle serves as a barrier that protects the area where the nail grows from bacteria, fungi, and other pathogens that could cause infections. By sealing the space between the nail and the surrounding skin, the cuticle plays a crucial role in maintaining nail health and integrity.

Understanding the protective nature of the cuticle is important, as without it, the area around the nail would be more susceptible to infections, which can lead to more serious complications. This protective function highlights the importance of proper cuticle care in both aesthetic and health aspects within nail care practices.
