The nail plate is created in the matriz de uñas, where skin cells are modified and keratinised to become the hard, flat cells of the nail plate. It is the most visible part of the whole nail unit, covering the area from the nail matrix to the free edge and beyond. While it may appear to be one piece, it is constructed from multiple layers of nail cells. As it grows it moves across the nail bed, held in place to the dermis beneath by nail bed epithelium, and kept within the lateral nail folds by the nail grooves along each of the sidewalls.

The tough upper layers are slightly thicker than the lower layers and form a protective barrier. These upper layers should NEVER be buffed off during any nail service. Buffing the top layers off exposes softer layers below.

This can affect the adhesion of any artificial products, such as regular nail varnish, UV gels or powder polymer or liquid monomer. It also weakens the nail and opens it up to penetration by unwanted substances. The lower and younger layers are attached firmly to the nail bed epithelium which, in turn is attached to the nail bed by a series of grooves.

Nail technicians carry out physical and chemical procedures to beautify, extend and enhance the nail plate’s appearance; and as professionals we have a responsibility to maintain and enhance the nail plate’s health.

¿Cuál es la función de la lámina ungueal?

La función de la lámina ungueal es crear una rigidez en el extremo del dedo que permita a los dedos funcionar eficazmente en todas sus necesidades de destreza, por ejemplo, coger objetos pequeños. También protege el último hueso de los dedos de manos y pies, que de otro modo se dañaría fácilmente.

¿Seguirá creciendo la lámina ungueal?

The nail plate is continuously formed from the matrix of the nail unit. Modified skin cells keratinise in the matrix and push older cells forward.  The journey from the matrix (which is a delicate area under and behind the base of the nail) to the free edge takes approximately 5 months.

¿Crecen las uñas desde el lecho ungueal?

Las uñas no crecen a partir del lecho ungueal. El lecho ungueal es una zona bajo la uña donde ésta se une al extremo del dedo y le proporciona aceites esenciales y humedad para mantenerla sana y flexible. Las uñas crecen a partir de una zona bajo la piel en la base de la uña llamada matriz
