Science
Mechanism of Action
Lactococcus/Hyaluronic Acid Ferment Filtrate operates as an effective humectant, drawing and retaining moisture within the skin to boost overall hydration. The Lactococcus ferment component is crucial for restoring and fortifying the skin's natural protective barrier and stimulating the synthesis of antimicrobial peptides, which are essential for maintaining a robust and healthy skin flora. Through the fermentation process, a complex array of bioactive compounds, including peptides, enzymes, and various acids, are generated. These contribute to enhanced hydration, reinforce the skin barrier, support overall skin well-being, and modulate the skin's microbiome. This modulation fosters a harmonious microbial balance, delivers antioxidant protection, and encourages cellular rejuvenation. Furthermore, the lactic acid bacteria byproducts can establish a protective film on the skin, effectively preventing water evaporation, strengthening the skin cuticle, and contributing to the equilibrium of the skin's water and oil content.

Optimal pH values, such as pH 7 or 7.2, observed in certain research contexts specifically pertain to the conditions for microbial production of hyaluronic acid during fermentation, not the stability of the final ferment filtrate ingredient in cosmetic formulations.
Safety
Safety Profile
While Lactococcus/Hyaluronic Acid Ferment Filtrate has not been individually reviewed by the CIR Expert Panel based on available data, related 'Lactobacillus Ferment Ingredients' (including Lactobacillus Ferment Filtrate) were concluded to be 'safe as used in cosmetics' by CIR in June 2025. These related ingredients are used at concentrations up to 5.6% in face and neck products. The active components are primarily byproducts of bacterial fermentation, not live bacteria. This ingredient is rated as 'Irritant Free' and 'Teen SAFE' by SkinSAFE and shows 'No penalty' across all categories on INCI Beauty. Hyaluronic Acid produced via fermentation has also demonstrated non-irritating properties in human patch tests.
