A custom fabricated (e.g. custom shaped and dimensioned) wound dressing that matches a corresponding, pre-mapped integumentary wound includes one or more liquid flow barriers composed for example of a hydrophobic and high viscosity liquid embedded in a layer of the dressing. One such embedded hydrophobic liquid barrier covers a skin section immediately adjacent to the wound opening so as to protect the skin section from harmful liquids such as exudates or water. In one embodiment, the skin protecting barrier is substantially comprised of a silicone oil having a viscosity in the range of about 100 cSt to 1000 cSt.
