Postbiotics, non-viable microbial components or metabolites derived from probiotics, represent a promising new class of therapeutic agents in dermatological and wound-healing science. This review highlights the bioactive potential of postbiotics in modulating inflammation, enhancing tissue regeneration, and restoring microbiota balance in skin wounds. Through analysis of recent experimental and clinical studies, postbiotics were found to accelerate wound closure, stimulate collagen synthesis, and improve barrier integrity while providing antimicrobial and immunomodulatory benefits. Their incorporation into topical formulations and wound dressings has shown to regulate moisture, prevent infection, and support optimal healing conditions. In contrast to live probiotics, postbiotics are stable, safe, and free from viability-related limitations, making them ideal for cosmetic and medical use. Overall, postbiotics represent an innovative, next-generation strategy for skin regeneration and wound management.
