Emerging research highlights the complex interplay between the gut microbiome, skin health, and environmental exposures, forming what is now recognized as the gut–skin–exposome axis. This narrative review explores the role of gut microbiome dysbiosis—a disruption in the balance of intestinal microorganisms—in the pathogenesis and progression of various non-communicable inflammatory skin diseases, including acne, atopic dermatitis, psoriasis, rosacea, systemic lupus erythematosus, chronic spontaneous urticaria, hidradenitis suppurativa, and alopecia areata. This review synthesizes mechanistic studies, clinical trials, and Mendelian randomization data to elucidate how altered gut microbial composition contributes to systemic and cutaneous inflammation. Key modifiable factors, such as diet, antibiotics, stress, and sleep, as well as interventions like probiotics, prebiotics, synbiotics, and fecal microbiota transplantation, are discussed for their potential therapeutic value. By integrating clinical insights with microbiome science, this review underscores the importance of a holistic, systems-based approach in managing inflammatory skin diseases, offering clinicians evidence-based strategies to improve patient outcomes through gut microbiome modulation.
