DuoDerm CGF - Triangular Hydrocolloid Dressing with Border is highly conformable and can be used on hard to bandage areas because it can be gently molded into place. The adhesive border doesn't require additional tape and when it is removed the bandage comes off in one piece. The dressing can be used on dermal ulcers including full-thickness wounds, pressure ulcers (Stage II-IV), leg ulcers, superficial wounds, partial thickness burns, and donor sites and can be worn up to seven days. Duoderm CGF is a control gel formula that gels on contact when the bandage comes in contact with exudate. The bandage is impermeable to outside contaminants, so your wound is kept safe from outside sources of bacteria or other unwanted debris.
