Understanding the Skin Microbiome

Discover how you can help restore balance your skin's microbiome with prebitoic skincare and La Roche-Posay.

Understanding the Skin Microbiome

Referring to the complex ecosystem of micro-organisms that live on its surface, the skin’s microbiome is crucial to the way the skin looks, feels and functions. With approximately one million bacteria per square centimetre of skin, 500 types of bacteria have been identified.  While they might sound unpleasant, these bacteria in fact play a vital role in keeping your skin happy, healthy and free from sensitivity and even disease.

Populated by both ‘good’ and ‘bad’ bacteria, these microbial communities communicate with each other and the cells to boost immunity and strengthen the skin’s barrier. For a healthy, youthful-looking skin, a balanced microbiome with sufficient bacterial diversity is essential. When the microbiome is depleted, skin conditions such as sensitivity, acne and atopy arise. Read on to learn how you can help restore balance with prebiotic skincare and La Roche-Posay.

Why is the Skin Microbiome Important?

Put simply, a balanced and diversified microbiome is the foundation of good skin health. In an unbalanced microbiome the skin’s barrier is weakened, resulting in both moisture loss and increased penetration of environmental aggressors and allergens. This can in turn result in increased sensitivity, irritation and dryness, as well as being a precursor to inflammatory skin diseases including psoriasis, eczema and acne.

Signs Your Microbiome is Out of Balance

Many factors can impact the skin microbiome, from skincare and household products and washing habits, to pollution, UV radiation, medications and lifestyle factors such as diet and stress. Dryness, itching, sensitivity, tightness, redness and breakouts are all signs of a possible unbalanced skin microbiome. Thankfully, a healthy microbiome can be restored with the help of prebiotic skincare.

The Power of Prebiotics

Increasingly, dermatologists and skincare formulators have been singing the praises of prebiotics in skincare, particularly for sensitive skin. These naturally occurring nutrients do so by acting like a fertiliser – creating the ideal environment for a harmonious microbiome and in this way, they help restore the optimal bacterial balance required for healthy and resilient skin.

La Roche-Posay’s Prebiotic Skincare

Central to La Roche-Posay’s healthy skin philosophy, prebiotics are the first step towards a beautifully balanced skin microbiome, and a better life for sensitive skin. Due to its unique combination of nutrients and minerals including magnesium and selenium, La Roche-Posay Thermal Spring Water is a prebiotic thermal spring water with proven skin-soothing properties. Used within the La Roche-Posay products, the antioxidant-rich water is also available in a convenient spray. Sprayed as needed, it immediately soothes and refreshes sensitive skin, while helping to support a healthy skin microbiome.  The benefits of prebiotics extends beyond the Thermal Spring Water however, so read on to find out what other La Roche-Posay products feature microbiome supportive prebiotics.
