What is the purpose of the cuticle in nails?

The cuticle serves a crucial role in protecting the underlying nail matrix and the area around the nail. Its primary function is to prevent injury and infection by forming a seal. This barrier helps to keep out harmful bacteria, fungi, and other pathogens that could potentially enter and cause infections. Additionally, a healthy cuticle contributes to the overall health of the nail by maintaining moisture and preventing damage, thereby ensuring that the nail can grow without interference. This protective aspect is vital for maintaining the integrity and health of both the nails and the surrounding skin.
