What it is: The top surface of the nail, from eponychium to extension edge, when looking at the enhancement from the side view.
What it is: A fold of skin at the base of the nail plate working in unison with the eponychium to seal and prevent pathogens from entering the nail’s matrix.
What it is: The part of the natural nail plate that extends beyond the fingertip. Also known as the distal edge of the nail unit, the free edge is the very tip of the nail plate.
What it is: Thin layer of translucent dead tissue, which the eponychium (living tissue) sheds. After being shed, the cuticle adheres to the nail plate. The eponychium, also known as the proximal nail fold, forms a seal to keep pathogens from entering and infecting the matrix area. The eponychium, which borders the base of the nail plate, is gently pushed back during nail prep/manicure service, whereas the cuticle is gently scraped off to create a clean base.
