Start here if you want to understand how gut health and skin health are connected. These introductory guides explain the gut–skin axis, the role of the gut and skin microbiomes, and how immune signalling, microbial metabolites, diet, stress and the body’s protective barriers may influence your skin.

You will learn how your gut can affect your skin, why skin health involves more than topical products and what happens when microbial ecosystems become disrupted. The evidence supports an important connection, but it does not mean that every skin problem begins in the gut or has one simple cause.
