BACILLUS/PRUNUS MUME FRUIT EXTRACT FERMENT FILTRATE.

Valuable / ANTIMICROBIAL, ANTIOXIDANT

A bio-transformed botanical extract derived from the Japanese Apricot, enhanced through specialized Bacillus fermentation to unlock concentrated bioactive metabolites. This postbiotic-rich filtrate delivers multifunctional benefits, ranging from gentle enzymatic resurfacing to robust antioxidant protection.

Antioxidant Antimicrobial Skin Conditioning Mild Exfoliant Microbiome Support

Science

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.

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
