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.
