Science
Mechanism of Action
Lactobacillus/Grape Juice Ferment Filtrate comprehensively supports the skin's ecosystem by nurturing the microbiome and reinforcing the skin barrier. Through the fermentation process, Lactobacillus bacteria produce a rich array of beneficial compounds including amino acids, peptides, organic acids (such as lactic acid), enzymes, and potent antioxidants. These constituents work synergistically to maintain a healthy skin pH, gently promote cellular renewal through mild exfoliation, and significantly enhance hydration. Functioning as a cell-free extract, it acts as a prebiotic, encouraging the proliferation of beneficial skin bacteria while concurrently calming irritation and offering robust antioxidant protection against pollution and oxidative stress. Studies suggest its capacity to reduce signs of sensitivity, including stinging and itching, potentially mitigating conditions like acne and rosacea by harmonizing the skin's microflora. Furthermore, in vitro research indicates its role in boosting oxygen uptake, stimulating collagen production, and enhancing ATP synthesis, with the fermentation process itself augmenting the ingredient's overall antioxidant capacity.

Key findings
- 01 Lactobacillus Ferment Lysate Filtrate at a 5% concentration demonstrated a 47% reduction in skin redness in an in-vivo study involving 5 participants.
- 02 Lactobacillus Ferment at 5% was shown to possess effective anti-acne properties.
- 03 A 1% concentration of Lactobacillus Ferment yielded positive results in mitigating skin sensitivity.
Transparency
Dusting Analysis
Effective concentrations for targeted benefits, such as reducing redness and sensitivity, range from 1% to 5%, which aligns with safe usage levels up to 5.6%. This indicates that meaningful concentrations are required for efficacy, reducing the likelihood of 'dusting' where an ingredient is included at an ineffective, token percentage.
The Formula
Formulation
Stability
Maintains stability within a pH range of 3.0 to 7.0. The natural fermentation process can lower pH. If utilized for its preservative qualities, it may require pH adjustment or co-preservatives for a complete and effective preservation system.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Lactobacillus Ferment, along with its filtrates and lysates, is safe for use in cosmetic formulations. This safety extends to applications near sensitive areas such as the mouth and eyes, as well as in baby products. The ingredient primarily consists of beneficial byproducts of bacterial fermentation, not live bacteria, and complies with established safety standards including European Cosmetics Regulation.
