Understanding Skin Repair

What is skin injury?

  • Occurs when any part of the epidermis is damaged
  • Cut, tear (abrasion), acne, burn, scalding, (hot water),
  • sunburn, surgery
  • Skin injury is skin wound

How does a wound heal?

  • Healing & repair is a critical part of self-protection in all
  • living things
  • Wound healing is skin healing
  • A very complex process
  • Begins immediately when injury happens
  • May be fast or may take years

Happens in various stages :

1. Hemostasis – stop the bleeding

  • Prevent blood loss
  • Close the wound with a clot
  • Platelets aggregate at injured site of blood vessel
  • Fibrin clot is formed
  • Wound is closed within about one minute

2. Inflammation – swelling

  • Once the wound is closed, repair process begins
  • Vasodilation – blood vessels enlarge, blood flow increases
  • To the injured area
  • Plasma, nutrients, growth factors, repair and healing cells
  • Leak out through blood vessels wall into the injured area
  • This causes swelling, redness, heat & pain
  • Important signals to the body
  • White blood cells remove dead tissues, bacteria
  • Pain warns the body that this area is injured; limits activity
  • Natural process that signals start of repair
  • No good if excessive or becomes chronic

3. Proliferation – rapid tissue growth

  • Growth factors brings about rapid growth of new
  • Tissues (collagen & cell matrix)
  • Network of new blood vessels formed so that new
  • Tissues can receive proper nutrients for growth
  • New epithelium covers the new tissues

 4. Remodelling – “putting the house in order”

  • Wound closes
  • Repair cells, having done their work, die by themselves
  • Collagen remodelled to become more organized and stronger & more elastic
  • Process can take a few weeks to years

Excessive wound healing 

  • An abnormal process; not well understood
  • Prolonged inflammation
  • Excessive collagen formed, excessive matrix formed. e.g “keloid” and “hypertrophic scars”.
