Why Fermented Skincare Ingredients Matter During Menopause Menopause brings visible changes to the skin, from dryness and sensitivity to a loss of elasticity and comfort. These changes are not random. They reflect a shift in hydration, the skin barrier and the environment on the skin’s surface. This is where fermentation offers a different approach, one that supports how skin functions, not just how it looks.   What Are Fermented Skincare Ingredients? Fermentation is a natural process where beneficial microorganisms break down ingredients into smaller, more bioavailable forms. This process creates compounds known as postbiotics, along with amino acids, enzymes and antioxidants that the skin can more easily absorb. In skincare, this means ingredients that are more readily used by the skin and better aligned with its natural processes.   Why Fermentation Matters During Menopause During perimenopause, menopause and post-menopause, the skin’s needs change. Hydration levels decline, the skin barrier becomes more vulnerable and the surface environment where the microbiome lives begins to shift. Fermented ingredients support this environment by helping maintain hydration, supporting the barrier and contributing to overall skin comfort.   The Benefits of Fermented Ingredients for Menopausal Skin   Deep Hydration Support Fermented ingredients can help attract and retain moisture, supporting skin that feels dry or less comfortable. What this means: Skin feels more hydrated and better supported throughout the day.   Improved Ingredient Absorption The fermentation process breaks down nutrients into smaller molecules, making them easier for the skin to utilise. What this means: Ingredients can work more effectively within the skin.   Support for the Skin Barrier Postbiotic compounds help support the skin barrier, which plays an important role in maintaining hydration and protecting the skin. What this means: Skin feels less reactive and more resilient.   Calming Support for Sensitivity Fermented ingredients are known for their ability to help calm visible redness and support sensitive skin. What this means: Skin appears more comfortable and less reactive.   Support for the Skin Microbiome Fermented ingredients help support the environment where beneficial microorganisms live. What this means: Skin is better able to maintain hydration, comfort and overall balance.   The Microbiome–Menopause Connection The skin microbiome is the community of beneficial microorganisms that live on the surface of the skin. During hormonal transition, the conditions that support these microorganisms change. This can influence hydration, sensitivity and how skin behaves. Fermented ingredients, particularly those rich in postbiotics, help support this environment and contribute to overall skin comfort.   A Different Approach to Skincare Menopausal skin does not need more products. It needs products that understand what is changing. Fermented skincare represents a shift away from surface-level solutions and toward supporting the skin’s natural processes. By focusing on hydration, the skin barrier and the microbiome, this approach helps skin feel more comfortable, more resilient and better supported through change.   Final Thought Fermentation may be an ancient process, but its role in skincare is increasingly relevant. For skin experiencing hormonal change, it offers a way to support what the skin needs, rather than trying to override it. And that is where real, lasting skin support begins.

Our Approach to Microbiome-Focused Skincare Not all skincare is designed with the skin’s microbiome in mind. Our mission is to research, develop and test formulations for optimal microbiome health. One of our main goals is to address skin dysbiosis, an imbalance in the skin's microbiome that can cause dryness, redness, acne and other issues. Understanding what causes dysbiosis is essential for creating skincare products that support a healthy skin environment.   Understanding the Skin Microbiome in Detail Recent advances in genetic sequencing have allowed us to analyse the skin microbiome in great detail. This helps us identify the specific strains of bacteria and other microorganisms on the skin, which we use to inform how we develop our formulations.   Beyond “Natural” or “Organic” Skincare Microbiome-focused skincare is more than just choosing “organic” or “natural” ingredients for marketing. We aim to ensure every element of a product serves a specific purpose. Depending on the product's goal, we include beneficial compounds such as:   Short-Chain Fatty Acids (SCFAs) These are produced by beneficial gut bacteria and offer health benefits such as reducing inflammation, promoting a healthy gut microbiome and supporting metabolic health. In skincare, SCFAs help strengthen the skin barrier, improve hydration and support smoother-looking skin.   Postbiotic Peptides These are small chains of amino acids produced by probiotic microorganisms. They help support collagen production, reduce inflammation and improve skin elasticity and firmness.   Bio-Fermented Botanicals Using our advanced strain-specific fermentation, we optimise the fermentation process to produce high-quality and effective botanicals. This is especially useful for extracting difficult or poorly absorbed bioactive compounds.   The Role of Fermentation During fermentation, microorganisms consume sugars and other compounds in the botanical material, producing metabolites like organic acids and enzymes. These enhance the bioavailability of the active compounds, making them more easily absorbed and effective. Fermented botanical actives also benefit the microbiome. Some microorganisms produce compounds that support the growth of beneficial bacteria on the skin, promoting a healthy and diverse microbiome.   Final Thought Using strain-specific fermentation to produce fermented botanical actives is an innovative way we create effective and safe ingredients for our skincare range.
