Science
Mechanism of Action
The fermentation process enhances the bioavailability and skin penetration of the active compounds within Camellia sinensis. This ingredient provides powerful antioxidant protection, neutralizing free radicals and shielding the skin from environmental stressors. It also exhibits strong anti-inflammatory properties, effectively soothing irritation and reducing redness. By stimulating collagen production, it contributes to improved skin elasticity and a more youthful appearance. Furthermore, it intensely moisturizes the skin, strengthening its protective barrier, and helps to balance the skin's natural microflora while mitigating epidermal damage. Components like lactic acid, generated by Lactobacillus, gently regulate skin pH, facilitate mild exfoliation of dead skin cells, and encourage the proliferation of healthy skin cells. Schizosaccharomyces cerevisiae further contributes anti-inflammatory, antioxidant, moisturizing, nourishing, and protective characteristics, alongside a spectrum of postbiotics including metabolites, enzymes, and peptides.

Key findings
- 01 Topical application of 6% Camellia sinensis glycolic leaf extracts (a key component) demonstrably increased immediate and long-term skin moisture, simultaneously improving skin microrelief and reducing roughness over 15-30 days of treatment.
- 02 A similar fermented bio-extract derived from Camellia sinensis, utilizing various probiotic strains including Saccharomyces cerevisiae, exhibited substantial antioxidant, anti-inflammatory (nitric oxide inhibition), and anti-aging (collagenase and tyrosinase inhibition) activities after 7 days of fermentation.

Dusting Analysis
The documented use of Lactobacillus Ferment and related ingredients at concentrations up to 5.6% for functional benefits, such as in face and neck products, indicates it is utilized for its efficacy rather than merely as a 'dusting' ingredient for label claims.
The Formula
Formulation
Stability
Fermentation intrinsically enhances the bioavailability and effectiveness of the active constituents. The fermentation process itself creates an acidic environment, with pH values observed to drop to 3.26-3.50. This ingredient is noted for its excellent compatibility, blending seamlessly with other cosmetic ingredients.
Safety
Safety Profile
The CIR Panel has concluded that Lactobacillus Ferment and related ingredients are safe for cosmetic application, with documented use up to 5.6% in face and neck preparations. Cosmetic formulators should be cognizant that postbiotics such as lactic acid, if present in sufficiently high concentrations, could potentially lead to skin depigmentation, requiring careful formulation to prevent such effects. In vitro ocular irritation studies indicate non-irritating results for Lactobacillus Ferment and closely related ingredients.
