Science
Mechanism of Action
The ferment filtrate is rich in beneficial compounds, including amino acids, peptides, organic acids (such as lactic acid), and enzymes, produced during the fermentation of walnut seed oil. It functions as an antioxidant by inhibiting oxygen-promoted reactions, thereby protecting cosmetic formulations from deterioration and skin from environmental stressors. Related Lactobacillus Ferment Filtrate studies indicate its ability to strengthen the skin barrier, calm irritation, foster a stable skin microbiome, and provide humectant properties for hydration, alongside exhibiting anti-microbial and anti-inflammatory effects.

Stability
This oil-soluble ferment filtrate is most stable within an acidic pH range of 3.61 to 4.70. This pH range is characteristic of many Lactobacillus fermentation processes, where reported values for similar ferments typically fall between 3.52 and 4.6.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) issued a 'Notice to Proceed' for the broader category of 'Lactobacillus Ferment Ingredients' in February 2025. This indicates that while a safety assessment is underway, there is currently insufficient published literature to conduct a formal Scientific Literature Review (SLR), and significant data gaps remain for this ingredient class.
