Science
Mechanism of Action
This multi-component ingredient enhances skin hydration by acting as a humectant, attracting and retaining moisture within the skin's layers. Its primary microbial components, Lactobacillus and Saccharomyces ferments, provide probiotic-like benefits by helping to neutralize toxins, maintain the skin's microbial equilibrium, and restore a healthy balance of bacteria on the skin surface. Beyond microbiome support, it offers antioxidant protection, stimulates collagen production, and is associated with improved skin elasticity, a reduction in the appearance of fine lines and wrinkles, and overall skin firming. Lactobacillus Ferment specifically functions as a DNA repair enzyme, fortifying the skin against environmental damage, and exhibits anti-microbial and anti-inflammatory properties beneficial for conditions such as acne and rosacea.

Dusting Analysis
As a ferment filtrate, this ingredient is typically a liquid, not a powder, and therefore not subject to dusting considerations.
The Formula
Formulation
Stability
While a specific optimal pH range for the stability of the final filtrate in cosmetic formulations was not identified, its constituent fermentation processes involving Lactobacillus and yeast generally occur in acidic to slightly acidic conditions. For instance, Lactobacillus fermentation with calcium carbonate typically maintains a pH between 6.5 and 7.0, and Saccharomyces cerevisiae operates optimally for ethanol production within a pH range of 4.0 to 5.0.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that related Lactobacillus Ferment ingredients (Ferment, Filtrate, Lysate, and Lysate Filtrate) are safe for use in cosmetics. Lactobacillus Ferment has been reported for use at up to 5.6% in various skincare preparations, including face and neck products. Saccharomyces Ferment Filtrate is also generally recognized as safe for cosmetic applications. The complete complex is listed in COSMILE Europe, affirming its use within the EU cosmetic market.
