DuoDerm Extra Thin - Square Hydrocolloid Dressing is intended for superficial wounds, dry to lightly exudating dermal ulcers, and as a protective primary dressing. Duoderm Extra Thin provides a waterproof barrier over the wound which helps protect it from bacteria and viral contaminates. The dressing can be removed from the wound without causing damage to the healing tissues. The top of the dressing is smooth so as not to catch clothes or bedding. This helps cut down on painful friction. Duoderm Extra Thin is comfortable and flexible making it easy to mold and fit, even in difficult areas. The dressing has an adhesive border and can be cut to fit. The Duoderm dressing gels when it comes into contact with light exudate to avoid leakage around the bandage. The extended wear time helps cut down on dressing changes, making Duoderm more economical. This square dressing is available in a variety of sizes to work with many different sized wounds.
