Traditional medicine has used the skin as a looking glass to find imbalances in the body for many years, and in more recent years, this connection has come into focus in modern medicine with the discovery of the gut-skin axis. The skin is the largest organ in the body, so it makes sense that it can act as an outward display of health issues. Inflammation in the gut shows up as inflammation of the skin, in all its different forms. Conditions such as acne, rosacea, psoriasis, and eczema all have an element of inflammation, and as such, are often a manifestation of something that is happening deeper within the body.
