ConvaTec’s Aquacel foam dressing combines an absorbent foam pad with the company’s proprietary Aquacel interface. The dressing has a waterproof barrier that allows for the evaporation of excess moisture and protection against viral and bacterial penetration, according to company data. Aquacel is engineered to gel on contact with wound exudate, so the dressing contours to the wound bed, minimizing dead space where bacteria can grow. The interface also maintains a moist wound environment that supports the body’s healing process. The dressing comes in a wide range of shapes and sizes and has a silicone adhesive designed to adhere only to the surrounding skin, not to the wound bed.
