The complex interrelationship between the gut microbiota and the skin, commonly known as the “gut–skin axis” has become a crucial field of study for comprehending skin health and illness. Systemic immunity, inflammation, and metabolism are all modulated by this two-way communication mechanism, which ultimately affects skin homeostasis. Numerous dermatological disorders, such as rosacea, psoriasis, atopic dermatitis, and acne vulgaris, have been linked to dysbiosis in the gut microbiota. On the other hand, the composition of the gut microbiome may be impacted by skin disorders. Highlighting the important microbial metabolites and immunological processes involved in this interaction, this abstract examines the current understanding of the gut–skin axis. It also talks about the possible therapeutic benefits of using probiotics, synbiotics, and prebiotics to target the gut microbiota to treat and prevent skin conditions. Gaining insight into this intricate interaction opens up exciting possibilities for creating innovative, all-encompassing dermatological treatment strategies.
