Collagen Wound Dressing 2"X2" 5PCS 100% Bovine Type I Collagen Sponge, High Absorbency (4x Fluid), Biodegradable, For Chronic & Acute Wounds

Accelerates Wound Healing with
Proven Results: Made from 100% bovine Type I collagen (the most abundant collagen in the human body), this dressing provides a natural scaffold that supports all stages of wound healing. In full-thickness skin excision studies, wounds healed within 4 weeks (28 days), with basic healing observed by day 14. A clinical study showed an 83.3 % wound closure rate (15 out of 18 patients) when switching to native Type I collagen for chronic wounds.
Biodegradable & MMP-Regulating: Acts as a sacrificial substrate for excess matrix metalloproteinases (MMPs), protecting the body's native collagen and allowing natural healing to proceed. Fully biodegradable, it degrades >95% within 3 weeks and is completely absorbed in less than 6 weeks, eliminating the need for painful removal and reducing dressing change frequency.
High Purity & Maximum Safety: Collagen purity with mixed protein < 0.2 %, ultra-pure and hypoallergenic.
Heavy metals: <10 ppm, safe for prolonged contact. pH balanced to match human skin, minimizing irritation. Viral inactivation validated at 9 logs (exceeds international standard of 6 logs).
BSE-free: OIE officially recognizes China as a negligible BSE risk region; full traceability reports accepted by FDA. Superior Exudate Absorption & Moisture Management: The porous sponge structure absorbs up to 40 times its own weight in wound exudate, 4x higher absorption than leading brands (Simpurity). This reduces the need for frequent changes, minimizes maceration, and helps maintain an optimal moist healing environment while preventing secondary trauma. Easy to Use & Customizable for
Multiple Wound Types: Non-adherent, easy-to-cut sponge that can be stacked for deeper cavities. Rapidly adheres to the wound bed without sticking to gloves or instruments. Available in sizes up to 20cm x 20cm (custom sizes available). Suitable for chronic ulcers, surgical wounds, pressure injuries, diabetic foot ulcers, traumatic wounds, and donor sites for use in hospitals, clinics, and home care
