The healing process involves the dynamic interaction of cells, extracellular matrix and tissue mediators. This process is generally divided arbitrarily into three phases: inflammation, tissue neoformation and remodeling of the extracellular matrix. In this last stage the orderly accumulation of collagen fibers and other constituents of the dermal matrix starting fibronectin, collagen type III and type I collagen is produced This process may be abnormal resulting in formation of hypertrophic scars or keloid, which occur as a result of excessive production of dense fibrous tissue during the healing process of a wound, often trivial. In both cases there is a greater number of cells that produce collagen profiles that are not found in normal skin or hypertrophic cicactrices no. In both cases there is an abnormally high content of type V collagen, related to the presence of numerous capillaries in these scars. Collagen compact nodules observed, often encapsulated with specific proteoglycans protease inhibitors protect them from degradation. In order to limit as much as possible the appearance of hypertrophic scars and keloids, and to reduce them once in place, these adherent polyurethane dressing act physically facilitating the prevention and reduction of hypertrophic, recent or old scars, and keloids. Consisting of two layers: the outer surface is a microporous polyurethane membrane and the inner film is an acrylic adhesive to facilitate attachment to the skin. It can be used to prevent scar hypertrophy and the appearance of keloid, in recent still hypertrophied scars. Reduce keloids caused by burns, general surgery or orthopedic injuries. The effects can be observed at 8-10 weeks of treatment, but the

The dressing can be trimmed to adapt its size to the desired area; reduces height and softens the color of the scar. Reduces scar discomfort. Contains no medicines; acts by a physical mechanism. Reduction of recent or old hypertrophic scars, or keloids, caused by burns, general surgery, cosmetic surgery or traumatic wounds. The dressing protects scars from sunlight, is flexible and waterproof. Polyurethane dressing consists of two layers: the outer surface is a microporous polyurethane membrane and the inner is an adhesive acrylic film for easy attachment to the skin.
