Skin barrier – a protection for our body

17 Sep , 2015  

Skin is the largest organ of the body. It protects other organs from external dust, pathogens and other harmful ingredients. It is a fine and thin layer doing a gatekeeper and defender’s job.

What is skin made of?

Three layers of skin

 

Skin consists of three layers:

  1. Innermost layer: It is a subcutaneous layer formed of fat. The fat layer helps to insulate the body from external temperature changes and body heat from getting dissipated.
  2. Second layer: This is a ‘Dermis’ layer containing all the nerve endings. It contains hair follicles, sensory nerve endings and blood vessels. This is the layer, which communicates brain about the pressure or pain felt by the skin.
  3. Third Layer: This outermost layer is called ‘epidermis layer’. It consists of layers of dead cells. The major function of this layer is to keep harmful substance away from the body. It is highly regenerative and replaces itself very fast on an injury.

The third layer provides ‘skin barrier’. It is made out of dead cells aka ‘stratum corneum’. Stratum corneum consists of ‘corneocytes’, which is bound together with lipids and fat layers known as ‘Lamellar Membranes’.
