Specialized Pro-Resolving Lipid Mediators and Dietary Omega-3/6 Fatty Acids in Selected Inflammatory Skin Diseases: A Systematic Review
Abstract
Specialized pro-resolving mediators (SPMs), including lipoxins, resolvins, protectins, and maresins, actively terminate inflammation and restore tissue homeostasis. This review addresses how specialized pro-resolving mediators (SPMs) and their omega-3/omega-6 PUFA precursors influence inflammatory pathways, disease mechanisms, and therapeutic potential across major inflammatory skin disorders. MEDLINE/PubMed was searched on 4 October 2025. Eligible studies included experimental, animal, mechanistic human, and interventional research examining SPMs or omega-3/omega-6 fatty acids. Non-English articles, reviews, conference abstracts, and dietary questionnaire–only studies were excluded. Two reviewers independently screened and extracted data. Due to heterogeneity, a narrative synthesis was performed. No formal risk-of-bias assessment was undertaken Of 359 records, 57 studies were included (26 psoriasis, 24 atopic dermatitis, 7 acne; scarce hidradenitis suppurativa data). Preclinical data consistently demonstrated that SPMs modulate key inflammatory pathways, support epithelial repair, and help restore immune balance. Human studies revealed altered cutaneous and systemic lipid mediator profiles—characterized by reduced omega-3–derived SPMs and predominance of omega-6-driven inflammatory mediators—suggesting impaired resolution mechanisms across these disorders. Interventional studies showed that omega-3 supplementation may reduce inflammatory markers, improve barrier function,…
