Collagen powder wound dressing in a 1-gram single-dose packet, designed for application to deep, irregularly shaped, or tunneling wounds where sheet or matrix dressings cannot achieve full wound contact. The powder form allows for thorough wound cavity filling, delivering bioactive collagen directly to the wound bed to support granulation and tissue repair. Suitable for use in skilled nursing facilities, home care, and post-acute wound management settings. Absorbs wound exudate while maintaining a moist healing environment. Frequently used in combination with secondary dressings as part of comprehensive wound care protocols for hard-to-heal wounds managed by wound care nurses and advanced practice clinicians.
