ConvaTec's DuoDERM CGF Sterile Dressing can help heal many types of dermal wounds and abrasions thanks in part to its many features. The dressing contains hydrocolloid, a sealing agent that forms when saturated by a fluid, typically exudate. The dressing works well at healing the skin from wounds of all types. These include full-thickened wounds, donor sites, leg ulcers and superficial wounds, among others. The dressing is the perfect size for covering smaller wounds.
