In plain English

This ingredient is made by fermenting sap from the Dendropanax tree and soybeans with beneficial bacteria. The fermentation process breaks down plant compounds into smaller pieces that skin may absorb more easily. It's used in skincare to help keep skin hydrated and calm, similar to how other fermented ingredients like galactomyces work.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A fermented blend of Dendropanax morbiferus sap and soybean filtrate, processed with Bacillus bacteria to create a bioactive mixture rich in amino acids, peptides, and antioxidants.

How it works

The fermentation creates smaller molecules that can penetrate the skin's surface, delivering moisture and supporting the skin's natural barrier. It may also provide antioxidant benefits by neutralizing free radicals.

Pros

Gentle hydration

The fermented molecules help attract and retain moisture in the skin without heavy oils, making it suitable for most skin types.

Barrier support

Amino acids and peptides from fermentation may help strengthen the skin's natural protective barrier over time.

Cons and cautions

Limited research

Most evidence comes from lab studies or traditional use; large-scale human trials are lacking, so benefits are not fully proven.

Potential allergen

Contains soy derivatives, which can trigger reactions in people with soy allergies, and Dendropanax sap may be unfamiliar to some.

Best for

  • People looking for gentle hydration boosters
  • Those interested in fermented skincare ingredients

Use caution if

  • Individuals with known allergies to soy or Dendropanax

Usage tips

Apply after cleansing and before heavier creams to maximize absorption.
Store products containing ferments in a cool, dark place to preserve potency.

Safety summary

Considered safe for topical use with low irritation potential. As with any new ingredient, patch test if you have sensitive skin or soy allergies.

Research notes

Early research suggests antioxidant and moisturizing properties, but peer-reviewed human studies are sparse. Most data comes from in vitro or traditional knowledge.

Common label clues
