Science
Mechanism of Action
This fermented filtrate exerts its effects through several key biological pathways. It acts as an antioxidant by efficiently neutralizing free radicals, thereby protecting against environmental stressors and reducing inflammation. It deeply hydrates by improving the skin's capacity for moisture retention and fortifying the epidermal barrier, enhancing suppleness and elasticity. The rich array of bioactive substances released during fermentation stimulates cellular regeneration, promotes cell renewal, and supports collagen formation, leading to smoother skin texture and a reduction in the appearance of fine lines. Furthermore, its anti-inflammatory and soothing properties actively diminish redness and irritation, contributing to a calm and balanced skin environment.

Key findings
- 01 A lotion incorporating 3% of a related fermented culture blend (Lacticaseibacillus rhamnosus and Lactobacillus paracasei) demonstrated a statistically significant reduction in skin redness and improved sensitive skin parameters after 30 days of twice-daily application.
- 02 Human Repeat Insult Patch Tests (HRIPTs) conducted with Lactobacillus Ferment at concentrations ranging from 4% to 10% were deemed non-irritating and non-sensitizing across 50-51 subjects, affirming its excellent skin tolerance.

Formulation
Stability
The Leuconostoc ferment component of this filtrate exhibits thermal stability up to 60°C (140°F) and should be integrated into formulations during the cooling phase, below this temperature, to maintain integrity.
Conflicts
- Highly anionic ingredients
- Certain thickeners, such as xanthan gum, if introduced prior to the ferment during the cooling phase of formulation
Safety
Safety Profile
The CIR Expert Panel concluded that this class of ferment ingredients is safe for cosmetic use. Its active components are beneficial byproducts of fermentation, not live bacteria. Formulators should be cognizant of potential tyrosinase inhibition, which may result in a skin lightening effect, ensuring this aligns with the product's intended function.
