Science
Mechanism of Action
The fermentation process utilizes Bacillus bacteria to enzymatically cleave complex plant polysaccharides and proteins into low-molecular-weight organic acids (such as citric and malic acids), amino acids, and peptides. This molecular refinement significantly improves skin penetration, where these compounds function as natural humectants and mild Alpha Hydroxy Acids (AHAs) to accelerate cellular turnover. Simultaneously, the ferment produces postbiotic metabolites that strengthen the skin's microbiome and neutralize reactive oxygen species (ROS) to mitigate environmental oxidative stress.

Dusting Analysis
Due to its complex INCI name and botanical origin, brands often include this ingredient at 'label-only' concentrations (below 0.5%). To achieve the documented antimicrobial and exfoliating benefits, a minimum threshold of 1.0% is required.
The Formula
Formulation
Stability
The filtrate is heat-sensitive; formulation temperature must remain below 40°C to prevent the degradation of secondary bio-active metabolites. It is highly stable in aqueous systems and O/W emulsions.
Synergies
- Hyaluronic Acid
- Niacinamide
- Other postbiotics
Conflicts
- Strong oxidizing agents
- High electrolyte concentrations
- Extreme pH levels outside 3.5-8.0
Safety
Safety Profile
While the specific filtrate is undergoing broader review, its parent components (Prunus Mume and Bacillus ferment) are established GRAS (Generally Recognized as Safe) ingredients with a history of low irritancy.
