Science
Mechanism of Action
The efficacy of this ferment filtrate stems from its rich byproduct profile, generated through microbial transformation of the botanical substrates. It functions fundamentally as a 'SKIN PROTECTING' agent, enhancing the skin's barrier integrity. The fermentation significantly increases the concentration of active biomolecules such as peptides, polysaccharides, polyphenols, and lactic acid. These components collectively confer potent antioxidant and anti-inflammatory properties, providing comprehensive skin conditioning. Furthermore, specific Lactobacillus metabolites may influence melanogenesis and immune modulation, offering potential benefits for conditions like hyperpigmentation and inflammatory skin states such as atopic dermatitis.

The Formula
Formulation
Stability
This ingredient is optimally stable within a pH range of 3 to 6, with a more commonly cited effective range of 4 to 6. A slightly acidic environment, exemplified by the pH 5.5 used during jujube fermentation, is conducive to its stability and activity. Formulations incorporating this ferment may necessitate careful pH management and the use of co-preservatives to ensure product integrity and longevity.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed related 'Lactobacillus Ferment' derivatives safe for cosmetic use, with maximum reported concentrations reaching 1.5% in certain applications like makeup bases. In vitro EpiDermTM assays predicted undiluted Lactobacillus Ferment and its filtrates/lysates to be non-irritating. Human use studies with similar ferment filtrates also reported no irritation. Although this specific complex ingredient lacks individual regulatory approval, its components are widely used and subject to general cosmetic safety regulations, indicating a favorable safety profile.
