Your skin is a sensitive, dynamic interface between you and the outside world.
Your skin is the only organ that meets the rest of the outside world and the only organ in which you can see damage.
- The largest organ of the body
- Retains body fluids, thus preventing dehydration
- Prevents infection
- Helps to regulate your temperature
- Sensory organ full of nerve endings
Although the skin has many layers, it can generally be divided into three main parts:
- Epidermis – The outer part contains skin cells, pigment (Melanocytes), and proteins.
- Dermis – The middle part contains blood vessels, nerves, hair follicles, and oil glands. The dermis provides nutrients to the epidermis.
- Subcutaneous layer/ Fatty Tissue – The layer under the dermis containing sweat glands, some hair follicles, blood vessels, and fat.
Each layer contains connective tissue with collagen fibres to give support and elastin fibres to provide flexibility, suppleness and strength.
