Ingredient review
Fermented Dendropax Sap Extract
INCI: LACTOBACILLUS/DENDROPANAX MORBIFERUS SAP FERMENT FILTRATE
A fermented sap extract that may offer soothing and conditioning benefits, but research is still limited.
In plain English
This ingredient is made by fermenting the sap of the Dendropanax tree with friendly bacteria (Lactobacillus). The fermentation process breaks down the sap into smaller molecules that may be more easily absorbed by the skin. It is thought to help calm irritation and keep the skin feeling soft and smooth, though most of the evidence comes from lab studies rather than large human trials.

What it is
A fermented filtrate derived from the sap of the Dendropanax morbiferus tree, processed with Lactobacillus bacteria to create a skin-conditioning ingredient.
How it works
The fermentation process produces peptides, amino acids, and other bioactive compounds that may help reduce inflammation and support the skin's natural barrier. It is believed to work by calming irritation and providing antioxidant-like effects.
Pros
Gentle soothing potential
Lab studies suggest it may calm redness and irritation, making it a good option for sensitive skin types.
Fermentation may boost absorption
The fermentation process breaks down larger molecules, which could help the skin absorb beneficial compounds more easily.
Cons and cautions
Limited human evidence
Most research is from lab or animal studies; large-scale human trials are lacking, so effectiveness is not fully proven.
Potential allergen risk
As a plant-based ferment, it may cause allergic reactions in people sensitive to tree sap or related botanical extracts.
Best for
- People with sensitive or easily irritated skin
- Those looking for gentle, fermented skincare ingredients
Use caution if
- Individuals with known allergies to Dendropanax or related plants
- Anyone seeking strong, clinically proven anti-aging effects
