Wound infection represents a significant challenge in clinical practice. Traditional wound management, targeting sterility and relying on strategies of broad-spectrum bactericidal activity and antibiotic dependence, achieves partial infection control but induces severe complications, including exacerbated bacterial resistance and skin microbiota dysbiosis. With the continuous advancement of microbiome research, a novel consensus has emerged: the key to wound healing lies not in the complete eradication of all microorganisms but in maintaining the dynamic balance of the microbial ecosystem. This review aims to elaborate on the paradigm shift from “bactericidal eradication” to “microbial modulation” in wound care, analyze the inherent limitations of conventional antibacterial strategies, and systematically summarize the critical roles of skin commensal microbiota in promoting wound healing through core mechanisms such as competitive inhibition, metabolic regulation, and immune modulation. Furthermore, it proposes that the core strategy of future wound care should focus on precision microbial modulation and discusses the application prospects of cutting-edge technologies, including probiotics, postbiotics, and individualized precision interventions. The innovative significance of this paradigm in wound dressing design is envisaged, emphasizing the development of novel materials integrating microbiota-specific regulatory capabilities and smart responsive functions. This work provides theoretical support for the precision prevention and control of wound infections, the improvement of healing quality, and technological innovation in the field of wound care.
