Facts About the Skin

This section aims to help you understand more about the skin.

What Is The Skin?

The skin is a strong, flexible barrier that protects the body against harmful substances (chemicals) and microorganisms (bacteria and viruses). The skin has three layers: The top layer of the epidermis (the outermost layers of cells in the skin) is called the stratum corneum, followed by the dermis and the subcutaneous layer.

The Skin Lifecycle

Skin cells have a lifecycle of about 21-28 days. Your body produces new cells in your deepest skin level. These skin cells gradually move up through the layers of your skin until they reach the outermost layer. They then die and flake off.

How The Skin Works

  • Defence
    The skin fights anything that can cause an allergy (allergens), which may penetrate the skin barrier.
  • Barrier
    The skin barrier protects the body from chemicals, UV light and injury.
  • Control of temperature
    Skin helps to regulate the body temperature through sweating. Sweat helps to cool the body.
  • Sensation
    Touch, temperature, pressure and pain.
  • Production of vitamin D
    Vitamin D is produced by the skin in response to the exposure of UV light. There are several vitamin D benefits for your body. It is essential for:
    • The formation of healthy and strong teeth, bones, and nails.
    • Healthy eyes.
    • The proper absorption of calcium by the body.
    • Maintaining a healthy immune system (protection against disease).
    • Lowers your risk of cancer (anti-carcinogen).
