Moisture around a wound can macerate the surrounding skin, so the goal is to create a protective barrier that keeps moisture away from periwound skin while still allowing care work to proceed. A petrolatum-based skin protectant does this by forming an occlusive film on the skin, sealing it and reducing both moisture contact and friction during dressing changes. Alcohol-based antiseptics around the wound dry and irritate skin, so they do not serve as a protective moisture barrier. Using no barrier provides no shield against moisture, and drying powders do not offer an effective, consistent barrier and can create other issues.
