Science
Mechanism of Action
This advanced ferment filtrate influences skin health through multifaceted pathways. It modulates the skin's resident microflora, thereby bolstering defense against environmental aggressors and minimizing epidermal compromise. Its rich biological profile provides intense moisturization and deep hydration, crucially fortifying the skin's protective barrier. For reactive or compromised skin, it delivers significant calming effects, effectively mitigating dryness and visible redness. The extract exhibits robust antioxidant capabilities, actively neutralizing damaging free radicals, and possesses a potent anti-inflammatory action. The fermentation process inherently enhances the bioavailability of its active constituents, promoting superior epidermal penetration and optimized biological efficacy, while also stimulating collagen synthesis. It actively contributes to maintaining optimal skin pH, facilitating gentle exfoliation of devitalized skin cells and encouraging the proliferation of healthy keratinocytes, largely attributable to lactic acid and other metabolic byproducts of the lactic acid bacteria. Furthermore, it generates natural antimicrobial compounds, including bacteriocins and hydrogen peroxide, which impart antibacterial properties and contribute to inflammation reduction. Short-chain fatty acids (SCFAs) are also produced, further contributing to its anti-inflammatory profile, alongside the release of intrinsic humectants such as amino acids and sugars, which collectively enhance skin hydration and barrier integrity.

Stability
The inherent pH of fermented tea leaf bio-extracts has been observed to range from approximately 3.26 to 3.50 after a 30-day fermentation period. However, a specific optimal pH range for this ingredient's stability within a finished cosmetic formulation has not been explicitly defined.
Safety
Safety Profile
The CIR Panel affirmed the safety of Lactobacillus Ferment, Lactobacillus Ferment Filtrate, Lactobacillus Ferment Lysate, and Lactobacillus Ferment Lysate Filtrate for cosmetic application, with their conclusion expected by June 2025. A specific mixture containing 2.00% Lactobacillus Ferment and 10% Camellia Sinensis Leaf Extract demonstrated non-irritating properties in an EpiOcularTM assay. This 2.00% maximum concentration specifically refers to the Lactobacillus Ferment component. No definitive SCCS or FDA status was identified for this exact combined ferment filtrate.
