When skin or organs are damaged, the body naturally wants to heal itself.
Since the body cannot re-create healthy skin or tissue, it puts together new fibres that are not as functional as the original tissue, but that serve as a protective barrier. When this barrier is completely healed, it is called as a scar.
Scar tissue is fibrous connective tissue and normally thicker than the surrounding skin tissue, it is paler and denser because it has a limited blood supply.
Although it takes the place of damaged or destroyed tissue, it is limited in function, including movement, circulation, and sensation. Other than with minor cuts and scrapes, scarring is a common result of any bodily damage due to surgery, infection or accident.
Surface Scar tissue is inferior to healthy normal skin for several reasons:
- Paler and denser due to limited blood supply
- Sweat glands are damaged or destroyed.
- Hair does not grow back.
- Less resistance to ultraviolet radiation (Sunburn).
Skin scars are normally flat and pale, but in some cases the body will produce too much fibrous tissue, resulting in an extra thick or raised scar.
