Science
Mechanism of Action
This ingredient operates through a synergistic dual mechanism. The Lactobacillus ferment, a natural probiotic, fortifies the skin barrier, helps balance the skin's microflora, and reduces sensitivity through its various beneficial byproducts, including peptides and organic acids. Concurrently, the fermented Scutellaria Baicalensis root extract acts as a powerful antioxidant and anti-inflammatory agent, diminishing redness, combating hyperpigmentation by inhibiting melanin production, and providing antimicrobial defense. The fermentation process enhances the extract's bioactivity, specifically stimulating keratinocyte differentiation and proliferation, which are crucial for improving skin barrier function, and boosting collagen production for enhanced skin firmness and repair.

Stability
The individual components, particularly Scutellaria Baicalensis Root Extract, are water-soluble. While optimal pH ranges for Lactobacillus fermentation processes are known (e.g., pH 5.8-6 for L. bulgaricus), specific pH stability for the final combined ferment filtrate in cosmetic formulations has not been explicitly determined. This ingredient is generally recommended for use at low concentrations.
Synergies
- The combination of Lactobacillus ferment and Scutellaria baicalensis root extract exhibits synergistic effects, enhancing overall skin barrier function, reducing inflammation, and promoting a healthy microbiome.
Safety
Safety Profile
The CIR Expert Panel has deemed Lactobacillus Ferment and its filtrates 'safe as used in cosmetics' (June 2025), with Lactobacillus Ferment alone used up to 5.6% in leave-on products. Scutellaria Baicalensis Root Extract is also concluded 'safe in cosmetics' (September 2020), with reported use up to 0.5% in leave-on products. Although individual components are well-studied for safety, a specific CIR assessment for the combined 'LACTOBACILLUS/SCUTELLARIA BAICALENSIS ROOT EXTRACT FERMENT FILTRATE' is not yet available. General guidelines suggest low concentrations are effective. Individuals with sensitive skin should perform a patch test due to the potential for mild irritation or allergic reactions.
