The ‘Skin barrier’ and the ‘Microbiome’ are real buzzwords in the skincare and beauty industry but what do they really mean and why are they important? 

Although absolutely integral to each other, your skin barrier and microbiome are two completely different things. 

What is the Skin Barrier? 

Your skin barrier is the outermost layer of your skin; the largest organ of your body. The skin barrier is often a likened to a brick wall – where specialised cells called corneocytes are the bricks and the mortar is a mix of lipids; fatty acids and ceramides and a substance called NMF – Natural Moisturising Factor which is packed with nutrients. Its’ role is to protect you by blocking out external aggressors such as extremes of temperature, bacteria, UV radiation and harm whilst locking in and balancing hydration on the inside. Extremes of temperature, harsh skincare actives, over-exfoliation, aging and UV radiation will all compromise your skin barrier resulting in inflammation and irritation seen and felt as tightness, redness, breakouts, soreness and dry flaky skin.

What is the microbiome? 

The microbiome is the term used to describe the trillions of organisms that reside on the skin and in the gut; these are primarily bacteria but also include viruses, fungi and mites.

When balanced, these micro-organisms co-exist in harmony to support our skin barrier, provide us with immunity and aid in the absorption of nutrients. At times, our microbiome can become imbalanced and the less beneficial organisms start to outnumber the beneficial ones in a process called ‘dysbiosis’ and we know that a number of dermatological conditions are linked to exactly this – for example dermodex mites in rosacea, Propionebacterium acnes in acne and delayed wound healing.

A healthy microbiome is acquired through good lifestyle habits and a healthy skin barrier – good sleep, drinking plenty of water, a diet rich in fruit and vegetables have all been shown to contribute to a healthy microbiome. But in our modern lives this isn’t always easy and antibiotic use, stress and poor diet can all contribute to dysbiosis.Along with these lifestyle factors, what we are doing to our skin is equally important. The use of harsh actives and over cleansing can be hugely detrimental and we must ensure that we are using skin care that supports our microbiome whilst nourishing and strengthening the skin barrier.
