Have you ever noticed that when you eat certain foods, your skin breaks out in acne or becomes dry and itchy? This is because of the gut-skin axis, a complex connection between your gut and skin.
Your gut and skin are connected through the gut-brain-skin axis, a bidirectional communication network that allows them to communicate with each other. When your gut is healthy, your skin is healthy too. But when your gut is out of balance, your skin can suffer.
The microbiome plays an important role in a wide variety of skin disorders. Not only is the skin microbiome altered, but also surprisingly many skin diseases are accompanied by an altered gut microbiome.
Dysbiosis in the skin and/or the gut microbiome is associated with an altered immune response, promoting the development of skin diseases, such as atopic dermatitis, psoriasis, acne vulgaris, dandruff, and even skin cancer.
The outer layer of your skin and the inner layer of your Gut is internally connected with Epithelial cells. Epithelial cells maintain an important link between the internal body and the external environment. They act as a first line of defense, preventing the entry of microorganisms and protects the pathogens from entering the body. The skin also contains antimicrobial peptides (AMPs), which is the second line of defense that help fight microorganisms. When the skin's barrier is broken, the body's second line of defense is activated.
Just how an impaired gut gives rise to skin conditions, similarly an altered layer of skin can change the composition of intestinal bacteria and increase the expression of host defense genes in the colon(which protects the gut).
