The cuticle is a layer of tissue whose main role is to seal the nail matrix. This layer of skin adheres to the nail plate, protecting the matrix at the root of the nail. The matrix, which is invisible to the naked eye, produces keratin and enables the nails to grow. The cuticle therefore protects the matrix and allows the nail to grow without infection or other problems.
It is worth noting that the cuticle is part of the stratum corneum. The skin, or more precisely the epidermis, consists of several layers, with the stratum corneum being the outermost layer and consisting of dead cells. When trimming the cuticle, the aim is to remove only dead tissue. Bleeding can occur if living tissue is cut.
