What is the function of a cuticle?

The cuticle serves an essential protective function for the nail matrix, which is the tissue under the base of the nail responsible for nail growth. The cuticle acts as a barrier, preventing bacteria and other pathogens from entering the sensitive area around the matrix. By doing so, it plays a critical role in maintaining nail health and preventing infections that could compromise the integrity of the nail and potentially lead to complications. This protective quality is vital, as any damage to the cuticle may expose the matrix to harmful organisms, resulting in various nail disorders or infections.
