Usually require a secondary dressing.
Collagen dressings are sheets, pads, particle and gels derived from bovine, equine, porcine or avian sources. These dressings encourage the deposition and organization of newly formed collagen fibers and granulation tissue in the wound bed.

• Maintain moist wound healing environment
• May be used with topical agents
• Conformable
• Nonadherent
