Skin the largest organ for the human body.Unlike some other organs, our skin is exposed to the environment and can be affected by external factors such as heat, humidity, pollution and chemicals.Our skin helps regular our body temperature and protects us from microbes and external elements.Our skin is also involved in sensations of touch, heat and cold.

Skin consists of 3 layers:

  • Epidermis is the outermost layer and acts as a barrier to the external environment. This later creates the skin’s tone. Melanocytes, which produce the pigment melanin which is responsible for our skin colour, are situated in this layer.
  • Dermislies below the epidermis and contains connective tissue, sweat glands and hair follicles.
  • Hypodermis is the deeper subcutaneous layer and consists of fat and connective tissue.
