General Information

The healing process of a skin wound follows a predictable pattern. A wound may fail to heal if one or more of the healing stages are interrupted. The normal wound healing stages include:

• Inflammatory stage – blood vessels at the site constrict (tighten) to prevent blood loss and platelets (special clotting cells) gather to build a clot. Once the clot is completed, blood vessels expand to allow maximum blood flow to the wound. This is why a healing wound at first feels warm and looks red. White blood cells flood the area to destroy microbes and other foreign bodies. Skin cells multiply and grow across the wound.

• Fibroblastic stage – collagen, the protein fibre that gives skin its strength, starts to grow within the wound. The growth of collagen encourages the edges of the wound to shrink together and close. Small blood vessels (capillaries) form at the site to service the new skin with blood.

• Maturation stage – the body constantly adds more collagen and refines the wounded area. This may take months or even years. This is why scars tend to fade with time and why we must take care of wounds for some time after they have healed
