Why Fermentation Is Growing in Personal Care
A Traditional Process Finding New Relevance in Modern Skin Care
Fermentation has been used for centuries in food, agriculture, and traditional preparations, but the process is finding new relevance in modern personal care. As formulators look for ingredients that combine natural origins with purposeful processing, fermentation offers a unique way to transform botanical and other naturally derived materials into ingredients designed for contemporary skin care, hair care, and personal care formulations.
From fermented botanical extracts to ingredients produced with Lactobacillus and Saccharomyces, fermentation is expanding the possibilities for naturally derived cosmetic ingredients.
Fermented Ingredients in Skin Care
Fermented ingredients are created by using microorganisms, such as yeast or bacteria, to transform a starting material under controlled conditions. Depending on the fermentation process, microorganism, substrate, and downstream processing, the resulting ingredient can have characteristics that differ from the original material.
This makes fermentation especially interesting for skin care. Rather than simply incorporating a traditional botanical extract, formulators can explore ingredients that have undergone an additional biological process before being incorporated into a finished formulation.
Fermentation has also become increasingly relevant alongside interest in the skin microbiome, postbiotics, biotechnology, and naturally derived skin care ingredients.
How Fermentation Can Unlock Botanical Benefits
Taking Botanical Ingredients a Step Further
Botanical extracts have long been used in personal care because plants are known to contain naturally occurring compounds associated with a variety of cosmetic benefits. Fermentation provides another way to explore those botanicals.
During fermentation, microorganisms produce enzymes and other metabolites as they interact with the starting material. These processes can break down or transform components within a botanical material, potentially changing their composition, accessibility, or functionality.
The result is a different approach to botanical ingredients: using biological processing to transform naturally derived materials and unlock new possibilities for personal care formulations.
This intersection of botanical extraction and fermentation technology provides formulators with another tool for developing natural and naturally derived ingredient stories with added technical depth.
Lactobacillus Ferments, Saccharomyces Ferments & Lysates
Different Processes Create Different Types of Fermented Ingredients
Not every fermented cosmetic ingredient is the same. The microorganism used and the way the fermented material is processed afterward can significantly influence the resulting ingredient.
Lactobacillus Ferments use bacteria from the Lactobacillus group during fermentation. These ferments have become particularly recognizable in skin care as interest in fermentation, microbiome-conscious formulation, and postbiotic ingredients has grown.
Saccharomyces Ferments use yeast, typically species of Saccharomyces, as the microorganism responsible for fermentation. Saccharomyces cerevisiae, commonly known as baker's or brewer's yeast, is one example used to produce fermented ingredients for personal care.
Lysation is different because it describes an additional processing step rather than a type of microorganism. During lysation, microbial cells are broken open, making intracellular components available within the resulting material. A ferment lysate therefore represents a fermented ingredient that has undergone this additional step after fermentation.
Understanding these distinctions can help formulators evaluate fermented ingredients based not simply on the word “ferment,” but on how the ingredient was produced and processed.
The Future of Fermentation in Personal Care
Fermentation sits at the intersection of several important areas of personal care innovation: natural ingredients, botanical extracts, biotechnology, microbiome-conscious skin care, and postbiotic ingredients.
For ingredient manufacturers and formulators, its potential goes beyond following a fermentation trend. Controlled fermentation provides another platform for transforming naturally derived materials and developing ingredients with new compositions, functions, and formulation possibilities.
As personal care continues to combine nature with increasingly sophisticated processing technologies, fermented ingredients are positioned to become an increasingly important part of the formulator's ingredient toolbox.
