Ingredient review
Fermented Botanical Oil Complex
INCI: Pseudozyma Epicola/Soybean Flour/Apricot Kernel Oil/Olive Fruit Oil/Sweet Almond Oil/Sunflower Seed Oil/Licorice Root Extract Ferment Extract Filtrate
A fermented blend of nourishing oils and licorice root extract that may offer gentle soothing and barrier support, though research on this specific complex is limited.
In plain English
This ingredient is a mixture of several plant oils (apricot kernel, olive, sweet almond, sunflower) and licorice root extract that have been fermented with a beneficial yeast called Pseudozyma epicola. Fermentation can break down larger molecules into smaller ones, potentially making the ingredients easier for skin to absorb and possibly boosting their soothing or antioxidant effects. It's used in skincare to help calm irritation and support the skin's moisture barrier.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A fermented filtrate created by combining soybean flour, apricot kernel oil, olive fruit oil, sweet almond oil, sunflower seed oil, and licorice root extract with the yeast Pseudozyma epicola. After fermentation, the mixture is filtered to remove solids, leaving a liquid rich in bioactive compounds.
How it works
The fermentation process by Pseudozyma epicola yeast can produce beneficial metabolites like amino acids, peptides, and fatty acids. These may help soothe skin by reducing inflammation and support the skin barrier by providing lipids and antioxidants. Licorice root extract is known for its calming properties, while the oils offer emollient benefits to soften and smooth skin.
Pros
Gentle Soothing Potential
The licorice root extract and fermentation process may help reduce redness and calm irritation, making it a good option for sensitive skin types.
Barrier-Friendly Oils
The blend of nutrient-rich oils like apricot kernel and sweet almond provides emollient fatty acids that help reinforce the skin's natural moisture barrier.
Cons and cautions
Limited Evidence
There is little published research on this exact fermented complex, so its benefits are inferred from the individual ingredients rather than direct studies.
Potential Allergen Risk
Because it contains multiple plant oils and soy flour, individuals with allergies to any of these components may experience a reaction.
Best for
- People with dry or dehydrated skin looking for barrier support
- Those with sensitive or easily irritated skin seeking gentle soothing ingredients
Use caution if
- Individuals with known allergies to soy, apricot, olive, almond, sunflower, or licorice
Usage tips
Safety summary
This fermented complex is considered safe for topical use in cosmetics. The individual oils and licorice root extract have a long history of safe use. The main risk is allergic reaction in sensitive individuals. Always patch test.
Research notes
Research on the individual components (e.g., licorice root extract for soothing, oils for barrier repair) is well-established. However, studies on this specific Pseudozyma epicola fermentation blend are scarce, so evidence is emerging rather than strong.
Common label clues
- Typical concentration
- Typically 1-5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used as intended. No specific restrictions.
- Common uses
- Serums, Moisturizers, Soothing Treatments
- Environmental note
- The oils are typically sourced from agricultural byproducts, and fermentation is a relatively low-energy process, but sustainability depends on specific sourcing practices.
Good to know
- Fermentation can sometimes reduce the irritation potential of raw ingredients, making this complex potentially milder than using the oils alone.
- The yeast Pseudozyma epicola is a non-pathogenic microorganism commonly used in biotechnology.
