The Skin

Is the largest organ in the human body and it:

  • accounts for up to 20% of human body weight
  • provides protection against mechanical injuries
  • protects against chemical (noxae) and physical irritants (heat, cold, light)
  • forms a barrier to prevent penetration of bacteria, viruses, mycoses and others
  • is responsible for heat regulation in the body
  • is responsible for sensory perception (pain, pressure, irritation, heat and cold)
  • performs metabolic functions (carbohydrates, proteins, lipometabolism,
    DNA & RNA synthesis)

The skin has a complicated structure.

Essentially it consists of three layers:

A - Upper skin or epidermis

B - True skin or dermis

C - Subcutaneous fatty tissue or subdermis


Every day, your skin is in contact with a wide range of physical irritants. Protecting the skin is imperative to healthy bodily functions.
