Scars are usually the result of damage to the body and are readily visible on the skin.
Collagen and scarring are the glue by which the human body heals wounds. Without the formation of deep scars, almost all skin wounds would split apart. When sewing or closing wounds, the author prefers to create a deep, hidden, strong scar for permanent binding because the deep scar takes the pressure off the surface tissues. The surface scar can then be minimized by proper tension and stitch techniques. Any surgery or wounding of the skin results in some scar formation.
