Science
Mechanism of Action
Operating through a dual mechanism, this ferment filtrate extract supports and enhances skin health. Lactobacillus ferment filtrates are known for their postbiotic content, which contributes to increased hydration, reduced inflammation, and a balanced skin microbiome, while also promoting cellular renewal and optimal skin pH. The fermented Schisandra extract introduces active lignans (polyphenols) and schisandrin, which are potent compounds providing significant antioxidant, anti-inflammatory, and adaptogenic benefits. This combined action effectively neutralizes free radicals, reinforces the skin's protective barrier, improves overall skin texture, and enhances luminosity, with potential to inhibit tyrosinase activity for brightening.

Stability
This ingredient maintains antioxidant activity and stability within a weak acid pH range of 2.98 to 6.25. While general Lactobacillus ferments can offer natural preservative properties, comprehensive efficacy often requires additional pH control or co-preservatives.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed similar Lactobacillus ferment ingredients (Ferment, Ferment Filtrate, Ferment Lysate, and Ferment Lysate Filtrate) safe for cosmetic use, with a maximum concentration of 5.6% for face and neck products. While no specific CIR assessment exists for this exact combined ingredient, its Lactobacillus ferment component has been found non-irritating in dermal and ocular irritation assays.
