Scar Healing

Scarring is a natural part of the healing process after an injury. Its appearance and its treatment depend on multiple factors.The depth and size of the wound or cut and the location of the injury matter. So do your age, genes, sex, and ethnicity.
When the skin is wounded and there is a break in the body's tissues, the body produces more of a protein called collagen, as part of the healing process.
Collagen builds up where the tissue has been damaged, helping to heal and strengthen the wound.



For a period of about three months or longer, new collagen continues to form and blood supply increases, causing the scar to become raised, lumpy and red. Some collagen then breaks down at the site of the wound, the blood supply reduces and the scar gradually becomes smoother, softer and paler. Although scars are permanent, they can fade over a period of up to two years. It is unlikely they will fade any more after this time.


Skin wounds can be caused by many things, including:
accidental injuries
surgery
burns and scalds
intentional harm
