Skin wound healing remains challenging due to a lack of ideal wound dressings suitable for acute and chronic wounds. This study introduced a biocompatible hydrogel wound dressing, synthesized through a green chemistry approach, specifically designed to meet the dual needs of acute and chronic wound care. The innovative strategy utilized sustainable biomaterials, soy protein, and vanillin, to construct a physical–reversible chemical dual-cross-linked hydrogel exhibiting high mechanical strength, excellent adhesion, and toughness. Schiff base reversible covalent bonds enabled rapid self-healing within 10 s, significantly improving durability. In a rat liver hemorrhage model, the hydrogel rapidly sealed wounds, achieving effective hemostasis, indicating great potential for acute wound care. Furthermore, vanillin imparted the hydrogel with antimicrobial and antioxidant properties, effectively accelerating diabetic chronic wound healing. This safe and efficient advanced biobased hydrogel offers a novel perspective for wound treatment and holds significant promise for clinical applications.
