Bio-fermented ingredients that nourish your good bacteria
BIO-FERMENTED SKINCARE: TREND, BENEFITS, AND HOW IT WORKS
The Science Behind Bio-Fermentation in Skincare
With skincare trends evolving faster than ever, bio-fermentation stands out as an innovative approach leading the way in modern cosmetic science¹,². By harnessing an ancient process and applying it to botanicals, scientists can create highly potent, effective ingredients that deliver real benefits for a range of skin concerns³,⁴.
While fermentation is most often associated with foods like Greek yoghurt, sourdough, kimchi, miso, or sauerkraut⁵, the same principle can be applied to skincare. Through controlled fermentation, natural plant materials are transformed into smaller, more bioavailable compounds¹,⁶ making them easier for the skin to absorb and unlocking new properties that boost performance²,⁷.
The Evolution of Fermentation
Fermentation is one of the world’s oldest preparation techniques, dating back thousands of years⁵. Originally used to preserve food such as milk, vegetables, and grains, it also enhanced flavour and nutritional value⁵. In the mid-1800s, Louis Pasteur identified that microorganisms, rather than “spontaneous generation”, were responsible for fermentation⁶. This discovery lead the way for pasteurisation and shaped modern microbiology⁶.
Today, cosmetic science applies the same principles to botanicals. By fermenting plant extracts with specific beneficial microorganisms, researchers can create new compounds with improved stability, potency, and skin compatibility²,⁷. This evolution has transformed fermentation from an ancient preservation method into an important modern skincare innovation².
How Does It Work?
Bio-fermentation uses microorganisms such as bacteria or yeasts to break down sugars and other natural materials in plant extracts¹,². As these microbes “feed”, they release metabolites like organic acids (eg: lactic acid), peptides & postbiotics ²,⁷. These by-products transform the original compounds into smaller, more active forms, improving their absorption, potentially reducing skin irritation, and sometimes even creating entirely new phytochemicals²,³.
The Benefits of Bio-Fermented Skincare
Bio-fermentation offers a wide range of benefits that make these ingredients especially valuable for skincare²,³,⁷:
-
Better Absorption - Large molecules are broken down into smaller ones, allowing actives to penetrate more effectively¹,².
-
Enhanced Performance - Fermented extracts show antioxidant, anti-inflammatory, brightening, and hydrating effects²,³.
-
Microbiome Support - Ferments nourish the skin’s natural flora, helping maintain balance and resilience³,⁸.
-
Sustainability - Many bio-ferments are created through upcycling, reducing environmental footprint,⁴.
-
Sensitive-Skin Friendly - Fermentation reduces potential irritants and enhances tolerability²,³.
-
Nutrient density - During fermentation, plants and algae release valuable compounds like peptides, enzymes, and vitamins, making bio-fermented formulas especially supportive for sensitive skin².

Bio-Fermented Skincare for Sensitive Skin: Why It Works
One of the standout advantages of fermentation is its compatibility with sensitive skin³,⁷. By breaking down complex compounds into gentler, smaller molecules, bio-fermented actives often reduce irritation while maintaining effectiveness.
Benefits include:
-
Keeping skin’s pH balanced³
-
Reducing dryness, irritation, and flare-ups³,⁷
-
Supporting microbiome balance³,⁸
-
Increasing tolerance in reactive or sensitive skin types³,⁷
This makes bio-fermented formulas particularly well-suited for conditions such as acne, eczema, or compromised barriers³,⁷.
The Future of Skincare
Bio-fermentation is not a passing trend- it represents a shift towards smarter, more sustainable skincare²,³,⁷. For consumers, this means formulas that are effective yet gentle, innovative yet grounded in science.
At Kioni Skin, we’ve designed our products with this in mind:
-
Sensitive-skin friendly - Gentle formulations that calm and support reactive skin.
-
Multi-tasking formulas - Combines multiple benefits in one step, simplifying your routine while saving time.
-
Sustainable and microbiome-focused - Eco-conscious ingredients that nourish the skin’s natural ecosystem.
-
Simplified routines without compromise - Streamlined products reduce layering and irritation while delivering effective results.
Our BARRIER PROTECT All-In-One Serum-Moisturiser combines serum power and moisturiser comfort in a single step- perfect for busy lives or anyone looking to reduce irritation caused by layering too many products. Together with the HYDRATE & BALANCE Multi-Biotic Cleanser, these formulas bring bio-fermentation science directly into your everyday routine³,⁷.
