Scar

Post Surgical Scars, New and Old Scars, Keloids, Hyperpigmented Scars, Acne Scars, Stretch Marks

Scars are areas of fibrous tissue (fibrosis) that replace normal skin after injury. A scar results from the

biological process of wound repair in the skin and other tissues of the body; thus scarring is a natural

part of the healing process. With the exception of very minor lesions, every wound results in some degree

of scarring. Scar tissue is exactly the same protein (collagen) as the tissue that it replaces, but the fiber

composition of the protein is different. Instead of a random basket-weave formation of the collagen fibers

found in normal tissue, in scarring, the collagen cross-links and forms a pronounced alignment in a single

direction. This alignment is usually of inferior functional quality to the normal collagen randomized alignment. For example, scars in the skin are less resistant to ultraviolet radiation, and sweat glands and hair

follicles do not grow back within scar tissues.
