Science
Mechanism of Action
This ferment employs a dual mechanism to support skin health. Firstly, it exerts broad-spectrum antimicrobial activity by acidifying the skin's environment and producing bacteriocins, specialized antimicrobial peptides that inhibit the growth of undesirable bacteria and fungi. Secondly, it functions as a humectant, actively drawing and binding moisture within the skin, which contributes to deep hydration, skin barrier fortification, and accelerated healing of irritated skin. The fermentation process also generates organic acids and other metabolites, potentially increasing antioxidant activity and stimulating the production of beta-defensins, integral components of the skin's innate immune system.

The Formula
Formulation
Stability
Lactobacillus Ferment is water-soluble and should be integrated into water-based systems or the water phase of oil-in-water emulsions. For optimal stability, it is recommended to add this ingredient during the cooling phase, ensuring temperatures remain below 70°C (158°F). Fermentation processes typically yield an acidic pH, often ranging from 4.0 to 5.5.
Safety
Safety Profile
The CIR Expert Panel has deemed Lactobacillus Ferment and related derivatives safe for cosmetic use. Formulators should be mindful of a potential skin lightening effect, which is considered a drug effect, and ensure usage does not lead to skin depigmentation. Comprehensive dermal irritation and sensitization studies indicate a low risk of irritation or sensitization, even at high concentrations.
