Pine & Soy Ferment Filtrate

INCI: BACILLUS/(PINUS DENSIFLORA/PARVIFLORA/THUNBERGII) LEAF/SOYBEAN FERMENT FILTRATE

A gentle, fermented botanical blend that may support skin hydration and antioxidant defense, but research is still emerging.

In plain English

This ingredient is made by fermenting pine leaves and soybeans with a type of friendly bacteria (Bacillus). The fermentation process breaks down the plant materials into smaller, more easily absorbed components like amino acids, peptides, and antioxidants. In skincare, it's used to help condition the skin, support moisture levels, and provide antioxidant protection against environmental stressors. Because it's fermented, it's generally considered gentle and suitable for many skin types.

Quick decision guide

Useful, but context matters

Pine & Soy Ferment Filtrate is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Pine & Soy Ferment Filtrate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

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 filtrate derived from a mix of pine leaf species (Pinus densiflora, Pinus parviflora, Pinus thunbergii) and soybeans, using Bacillus bacteria. The resulting liquid contains water-soluble compounds from the fermentation process.

How it works

The fermentation process breaks down larger proteins and carbohydrates in pine leaves and soybeans into smaller peptides, amino acids, and sugars. These smaller molecules can help support the skin's natural moisture barrier, provide antioxidant activity, and may have a mild soothing effect. The Bacillus bacteria themselves may also contribute beneficial metabolites.

Pros

Gentle antioxidant support

The fermentation process creates smaller, skin-friendly molecules that can help neutralize free radicals without irritation.

Hydration and barrier support

Amino acids and peptides from the ferment can help maintain the skin's moisture balance and support a healthy barrier.

Cons and cautions

Limited direct research

While individual components (pine, soy, Bacillus) have studies, there is little published research on this exact ferment blend's effects on human skin.

Potential allergen risk

Soy is a common allergen, and pine may cause reactions in sensitive individuals. Patch testing is recommended.

Best for

  • Anyone looking for a gentle, antioxidant-rich ingredient in their routine
  • Those interested in fermented skincare for added skin conditioning

Use caution if

  • Individuals with known allergies to pine or soy products should patch test first

Usage tips

Apply after cleansing and before heavier creams to allow absorption of the ferment's beneficial compounds.
Store products containing this ingredient in a cool, dark place to preserve the stability of the ferment.

Safety summary

This ingredient is considered safe for cosmetic use based on the safety of its components and the fermentation process. However, individuals with soy or pine allergies should patch test. There are no known serious safety concerns.

Research notes

Research on this specific ferment blend is limited. However, studies on pine extracts show antioxidant and anti-inflammatory properties, and soybean ferments are known for amino acid content. The Bacillus fermentation process is well-documented in food and cosmetic science.

Common label clues

Typical concentration
Typically 1–10% in leave-on products
Regulatory status
Approved for use in cosmetics in the EU, US, and Korea. No specific restrictions beyond general cosmetic ingredient safety.
Common uses
Serums, Essences, Toners, Moisturizers
Environmental note
Pine leaves are a renewable resource, and soybeans are widely cultivated. The fermentation process is generally considered low-impact compared to chemical synthesis.

Good to know

  • Fermented ingredients are often used in K-beauty and J-beauty routines for their gentle, conditioning properties.
  • The Bacillus bacteria used in this ferment are generally recognized as safe for cosmetic use.
