How Does Our Skin Help Us?

Written by rebeccah

The skin is the largest organ of the human body.

It is made up of three layers:

  • The epidermis: the outermost layer. This layer sheds dead skin cells and regenerates new cells to replace them.
  • The dermis: the middle layer. This layer contains elastic fibers and collagen to keep our skin supple and strong.
  • The subcutis: the innermost layer. This layer contains our adipose (fat) tissue which provides insulation and mechanical protection.
Layers of Skin: epidermis, dermis, subcutaneous tissue (fat).
The epidermis, dermis and subcutaneous tissue.

What does our skin do?

  • It allows our body to feel sensations such as touch, temperature, pain and pleasure.
  • Enables regulation of body temperature through sweating.
  • Provides a waterproof barrier protecting our bodies from the environment.

What happens if it is damaged?

  • Breaks in your skin provide an opening for different microorganisms to enter our bodies and potentially cause infection.
  • Extended exposure to UV rays increases your risk of developing skin cancer, wrinkles or age spots.
Signs of a damaged skin barrier: inflammation, dark spots and hyperpigmentation, rough, uneven skin texture, sensitivity or allergic reactions, fine lines and wrinkles, dull and dehydrated, breakouts, tightness and flaking or peeling, and rashes like eczema.
Signs of damage.

How can we maintain our skin?

  • Protect it from the sun: use sunscreen, avoid sun exposure between 10am and 4pm, and wear protective clothing. These steps minimise the risk of sun damage.
  • Avoid smoking: smoking can increase the risk of wrinkles, cancer and decreases the oxygen and nutrients present in the skin.
  • Drink plenty of water.
  • Eat a healthy, balanced diet.
  • Reduce stress levels.
  • Moisturise your face and body daily.
  • Use warm water instead of hot during a shower to avoid dehydration.
  • Regular skin checks by your GP or cancer clinic allows for early detection and treatment.
