Science
Mechanism of Action
This multi-beneficial complex operates through the synergistic action of its fermented components. Lactobacillus ferment filtrate supports skin hydration, fortifies the skin's natural barrier, and offers anti-inflammatory, antioxidant, and antimicrobial properties. It aids in balancing the skin's microbiome and pH, while promoting healthy cell renewal. Honey, transformed through fermentation, functions as an excellent humectant, drawing and retaining moisture. Chamomile flower extract, known for its calming and restorative qualities, contributes significant anti-inflammatory and antioxidant benefits, helping to mitigate redness and irritation. The fermentation process is observed to amplify chamomile's antioxidative activity.

Key findings
- 01 An in-vivo study involving 5 participants demonstrated a 47% reduction in redness with 5% Lactobacillus Ferment Lysate Filtrate, underscoring its soothing and anti-irritant potential.
- 02 Lactobacillus Ferment at 5% was identified as effective in addressing anti-acne concerns.
- 03 Application of 1% Lactobacillus Ferment showed efficacy in reducing skin sensitivity.
- 04 For similar Lactobacillus-fermented flower extract products, a concentration range of 0.1% to 90% is suggested for cosmetic formulations to achieve skin improvement effects; concentrations below 0.1% may not provide noticeable benefits.

Dusting Analysis
This ingredient is effective at practical cosmetic concentrations. Efficacy for similar fermented flower extracts begins at 0.1%, with specific benefits observed at 1% and 5% for its key ferment components. This indicates it delivers measurable results without commonly requiring excessively low, 'dusting' levels.
The Formula
Formulation
Stability
Optimal stability and effectiveness are observed within an acidic to slightly acidic pH range of 3.0 to 6.5. Fermentation typically lowers the pH, with Lactobacillus plantarum fermentation of chamomile reducing pH from 6.5 to approximately 3.3.
Synergies
- Ingredients that support skin barrier function
- Other humectants for enhanced hydration
- Antioxidant-rich botanical extracts
Conflicts
- Concentrations exceeding 90% of similar Lactobacillus fermented flower extract products may compromise formulation stability.
Safety
Safety Profile
The CIR Panel has deemed Lactobacillus Ferment, Lactobacillus Ferment Filtrate, Lactobacillus Ferment Lysate, and Lactobacillus Ferment Lysate Filtrate safe for cosmetic use (as of June 2025). Lactobacillus Ferment has been reported for use up to 1.5% in makeup bases. Chamomilla Recutita-derived ingredients are also concluded to be safe when formulated to be non-sensitizing, with reported maximum use concentrations up to 0.4% in eye lotions and 0.2% in shave balms.
