Understanding the skin microbiome

The skin is the largest organ of the human body, and on the surface lives an invisible world of bacteria, fungi and other microscopic organisms. This living ecosystem is your skin microbiome which sits on top of the skin barrier. A healthy microbiome and skin barrier not only maintain the health of the skin, but also supply essential molecules to nourish and protect the skin.

What is the skin microbiome?

The skin is home to trillions of bacteria, viruses, and fungi that function as a self-sustaining ecosystem, referred to as the microbiome. The skins microbiome is essential for both the health of the skin and our bodies overall immune health. It comprises over 1000 different species, all working together to regulate the skin’s pH level, protect from environmental damage and fight infections, while keeping the skin hydrated and youthful looking. The greater the diversity of the microbiome, the healthier the skin barrier is and the less likely the skin will be dry, red, or irritated. Recent research has also shown that the skin microbiome may play a role in other health conditions beyond the skin, such as autoimmune diseases and mental health conditions.

What is the gut-brain-skin axis?

The digestive system and the skin are connected in a physical and biochemical way and play an important role in defending the body against pathogens from the outside environment. The skin sends and receives signals to and from the brain, forming the gutbrain-skin axis. Dysregulation of the gut-brainskin axis has been implicated in the development of various skin conditions, including acne, eczema, and psoriasis, as well as mental health conditions such as depression and anxiety.

Prebiotics and the skin

Take care of your intestinal health by eating prebiotic and fibre-rich foods that can boost the skin’s ability to fight off unwanted bacteria and help improve the overall health of the skin and body.

Due to the important relationship between the skin and gut microbiome, a plant-based diet has been shown to have a large impact on gut health.

Another approach is using post-biotic skincare. Bacteria that have been grown and then killed serve as a food source for the helpful bacteria that naturally colonize healthy skin. This helps reduce inflammation within the skin in the same way that has been shown by taking oral probiotics.

The skin microbiome is an essential yet often overlooked aspect of our skin’s health. By understanding its role in inflammatory skin conditions, aging, and acne, you can take steps to nourish and support this delicate ecosystem. With a balanced skin microbiome, you can enjoy healthier, more radiant skin for years to come. eunoiabeauty.com
