Science
Mechanism of Action
This ingredient operates multi-functionally by first promoting a balanced skin microbiome through its Lactobacillus ferment lysate, fostering beneficial bacteria and offering protective qualities. Its diverse components, including hyaluronic acid, lactic acid, lipoteichoic acid, sphingomyelinase, and exopolysaccharides, collectively support cell renewal, boost collagen synthesis, improve hydration, and enhance elasticity, leading to a reduction in fine lines. The ingredient also exhibits antimicrobial efficacy against inflammatory bacteria and provides anti-inflammatory effects that significantly reduce redness and irritation. Furthermore, the fermentation process heightens the bioavailability and activity of Turmeric Leaf Extract's beneficial compounds, dramatically increasing its antioxidant capacity and anti-inflammatory power, while also guarding against UV-induced oxidative stress and facilitating mild exfoliation.

Key findings
- 01 An in-vivo study demonstrated a 47% reduction in skin redness when utilizing 5% Lactobacillus Ferment Lysate Filtrate.
- 02 Lactobacillus ferment, at a 1% concentration, has been shown to reduce skin sensitivity.
- 03 A 5% concentration of Lactobacillus ferment exhibited efficacy in providing anti-acne benefits.
- 04 A randomized study revealed that a blend of fermented lysates significantly improved skin moisturization, decreased transepidermal water loss (TEWL), and reduced redness over 30 days, particularly benefiting sensitive skin.
- 05 Fermented turmeric, processed with lactic acid bacteria, was found to prevent UV-induced oxidative stress in human fibroblast cells and showed enhanced antioxidant and anti-inflammatory properties compared to unfermented turmeric.

Dusting Analysis
This is a sophisticated, multi-faceted ingredient with documented clinical efficacy across a range of concentrations. Its complex mechanism involving both fermentation and specific plant extracts distinguishes it from commonly 'dusted' single-action ingredients.
The Formula
Formulation
Stability
The ingredient maintains stability under typical use and storage conditions for approximately one year. It is temperature stable up to 60°C, though for optimal integration into formulations, it should be added to the water phase, ideally below 40°C and after emulsion formation. Temporary appearance changes due to cold can be reversed by warming to 45-50°C. Avoid extreme temperatures and strong oxidizing agents.
Safety
Safety Profile
The CIR Expert Panel, as of June 2025, affirmed the safety of Lactobacillus Ferment and its filtrates/lysates for cosmetic use. In-vitro tests at 100% concentration showed no dermal or ocular irritation. A Human Repeat Insult Patch Test (HRIPT) on a product containing 5% of this ingredient confirmed a non-sensitizing profile.
