Science
Mechanism of Action
The ingredient delivers a potent blend of beneficial metabolites, including lactic acid, flavonoids (like quercetin and luteolin), sesquiterpene lactones (such as elenalina), organic acids, and peptides. Lactic acid gently exfoliates and boosts hydration, while flavonoids and sesquiterpene lactones offer significant antioxidant and anti-inflammatory protection. Organic acids condition skin and help maintain optimal pH, and peptides support skin regeneration. It acts as a humectant, drawing moisture into the stratum corneum, and the arnica component can stimulate microcirculation for a revitalized complexion. Furthermore, it helps balance the skin microbiome, reduce visible redness, improve elasticity, strengthen the protective barrier, and foster collagen synthesis.

Formulation
Stability
This ingredient is fully water-soluble, making it highly suitable for aqueous cosmetic formulations. Arnica extracts also exhibit clear and stable solutions when formulated with common glycols like propylene or butylene glycol.
Safety
Safety Profile
The CIR Expert Panel has deemed Lactobacillus Ferment and its filtrates safe for cosmetic use, with reported concentrations up to 5.6% in face and neck products. However, caution is advised due to the Arnica Montana component. While fermentation may reduce the allergenicity of raw arnica, unfermented Arnica Montana Flower Extract has been associated with contact dermatitis in some individuals, particularly those sensitive to sesquiterpene lactones. Individuals with known allergies to Arnica montana or extremely sensitive skin should exercise discretion.
