Throughout our lives, we all have experiences that injure our skin, leaving behind a scar. How you scar depends on many factors. Dr. Ed Hill tells us more about scars in todayís 60 Second Housecall.
Scars are a natural part of the bodyís healing process. A scar results from the repairing of a wound in the skin and other tissues. Most wounds, except for very minor ones, result in some degree of scarring.
Scars form when the dermis, a deep, thick layer of skin, is damaged. The body forms new collagen fibers to mend the damage, resulting in a scar. The new scar tissue will have a different texture and quality than the surrounding tissue. Scars form after a wound is completely healed.
Most scars are flat and pale. However, in cases when the body produces too much collagen, scars can be raised. Raised scars are called hypertrophic scars or keloid scars.
Some scars can have a sunken or pitted appearance. This kind of scarring occurs when underlying structures supporting the skin are lost. Some surgical scars have this appearance.
Although scars cannot be completely removed, their appearance can be improved. Methods for improving the appearance of scars include topical treatments, steroid injections, radiotherapy, dermabrasion, laser resurfacing, filler injections and, in some instances, surgery.
