Distribution and orientation of collagen reflects the function of the tissue in which it is found. For example, it is collagen that transmits tension in tendon, lends structural support in skin and bone and limits expansion in arteries. Collagen plays an integral part during each phase of wound healing and is an excellent hemostatic agent. It absorbs 40 - 60 times its weight in fluid. When applied to a wound, collagen initially acts as a hemostatic agent.
Continued application seems to aid and hasten the body's own repair mechanisms.
