INCI: Aloe Arborescens Leaf Extract, Lactobacillus/Soybean Ferment Extract, Glycerin
A fermented aloe complex that offers gentle hydration and soothing benefits, though research on the specific blend is limited.
In plain English
This ingredient is a mixture of aloe leaf extract and fermented soybean extract. The fermentation process is thought to break down the plant materials into smaller, potentially more absorbable components. It's used in skincare to help calm irritation and provide moisture without feeling heavy or greasy.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A fermented botanical blend combining Kidachi aloe (Aloe arborescens) leaf extract with a Lactobacillus ferment of soybean extract, often suspended in glycerin. This is a modern, biotech-inspired ingredient aimed at enhancing the traditional benefits of aloe.
How it works
The aloe component provides known soothing and hydrating polysaccharides, while the fermentation process may generate additional peptides and antioxidants from the soybean. Together, they help support the skin's moisture barrier and reduce visible redness or sensitivity.
Pros
Gentle Soothing
Helps calm redness and irritation, making it suitable for reactive skin types.
Lightweight Hydration
Provides moisture without a sticky or heavy feel, ideal for layering under sunscreen or makeup.
Cons and cautions
Limited Research
The specific fermented blend lacks extensive peer-reviewed studies, so its claimed benefits are based on traditional use and ingredient logic rather than robust clinical data.
Potential Allergen
Contains soy-derived components, which may trigger reactions in individuals with soy allergies.
Best for
- People with dry or dehydrated skin
- Those looking for a gentle, soothing ingredient for sensitive skin
Use caution if
- Individuals with a known allergy to aloe or soy
- Those who prefer non-fermented ingredients due to personal sensitivity
Usage tips
Safety summary
Considered safe for topical use in cosmetics. The main risks are allergic reactions to aloe or soy, and potential irritation from fermentation byproducts in extremely sensitive individuals. Patch testing is recommended for new users.
Research notes
Aloe vera's soothing properties are well-documented, but specific studies on Aloe arborescens and its fermentation with soybean are sparse. Most evidence is anecdotal or extrapolated from ingredient chemistry.
Common label clues
