Two square meters of skin cover our body, making skin the largest human organ. Healthy skin is important because it is the most visible part of our body. To look after your skin better and to make the right decisions about your cosmetic and medical needs, you need a good understanding of what skin is made up of.

As the outermost covering of the body, your skin is the first line of defence against pollution, microorganisms, radiation and physical trauma. Skin also regulates body temperature, cooling the body when it is hot and conserving heat when it is cold. It manufactures Vitamin D from sunlight and helps remove waste such as urea. As a sensory organ, skin enables us to feel heat, pressure, pain, touch and pleasure.


  • Epidermis (epi- means "on top of") - the outermost layer of the skin. A healthy epidermis looks clear and feels smooth. To remain healthy, old cells need to be replaced by new cells.
  • Dermis (dermis means "skin") - a healthy dermis gives the skin volume, firmness and a radiance when it is richly supplied with blood and moisture.
  • Subcutis (sub- means "below" and cutis is just another term for skin) - the innermost layer that acts like a cushion that insulates the body. It also acts like a cushion against shock to protect internal organs.
