Relação entre microbiota intestinal e cutânea: impactos na saúde da pele e o papel da alimentação

Abstract

Introduction: The gut-skin axis refers to the interaction between the intestinal and skin microbiotas, both essential for host homeostasis and health. Objective: This narrative review investigated the relationship between these microbiotas, their impacts on skin health, and the role of diet. Methods: The research was conducted in indexed databases using specific keywords and selection criteria, covering articles published between 2013 and 2024. Ten studies involving 6.237 participants from various regions were analyzed, exploring topics ranging from the influence of probiotics and prebiotics on skin health to the effects of dietary interventions. Results: The results demonstrated that alterations in the gut microbiota can lead to dysbiosis, contributing to inflammatory dermatological conditions such as acne, atopic dermatitis, rosacea, and psoriasis. Evidence suggests that dietary modulation, including the intake of fibers, prebiotics, probiotics, and supplements like collagen, improves both intestinal and skin microbiotas, benefiting skin health. Some studies highlighted the impact of synbiotics in acne treatment, while others showed that gut imbalances directly influence dermatological conditions. Conclusion: In conclusion, nutritional strategies hold promise for optimizing the microbiota-immune system balance, preventing and treating skin disorders. This research underscores the importance of integrative therapeutic approaches and encourages further investigations to better understand the interactions between diet, microbiota, and skin health, promoting effective and personalized interventions.
