ABSTRACT:
The present invention is a scar-reducing plaster and a method for preparing scar-reducing plasters. The scar-reducing plasters comprise a backing film comprising an air- and water vapor-pervious and water-impervious polymer layer, and a breathable and adhesive polyurethane xerogel matrix layer that coats the backing film. The polyurethane xerogel matrix layer includes a central scar contact region and an edge region, wherein the scar contact region merges with the edge region and the thickness of the edge region decreases from the scar contact region to a thickness of from 5 to 150 μm at the edge of the polyurethane xerogel matrix layer. The scar-reducing plasters of the present invention have a reduced tendency to peel off during normal use.
