Science
Mechanism of Action
This fermented extract delivers a complex blend of beneficial compounds including amino acids, peptides, organic acids, enzymes, and antioxidants to the skin. It actively supports a balanced skin microbiome by fostering beneficial bacteria growth and reinforcing natural defenses against harmful microorganisms. By strengthening the skin's barrier function, it minimizes transepidermal water loss, significantly improving skin hydration. Its calming properties help alleviate inflammation and irritation, while promoting cell renewal to refine skin texture and further fortify the barrier. Furthermore, it stimulates the production of vital beta-defensins in skin cells and, in studies on related Lactobacillus extracts, has demonstrated the ability to boost oxygen uptake, collagen synthesis, and ATP production, critical for cellular energy and repair.

Key findings
- 01 An in-vivo study indicated that a 5% concentration of Lactobacillus Ferment Lysate Filtrate effectively reduced skin redness by 47%.
- 02 Topical application of Lactobacillus Ferment Filtrate has been shown to mitigate signs of sensitivity, such as stinging and itching, while simultaneously enhancing hydration and offering protective benefits against environmental pollutants and oxidative stress.
- 03 Further research highlights its capacity to restore skin barrier strength, reduce irritation, stabilize the skin's microbiome, improve hydration through humectant actions, and provide significant antioxidant protection.

The Formula
Formulation
Stability
The fermentation process of coffee typically concludes in a slightly acidic pH range of 3.5-3.9, indicating ingredient stability under these conditions. However, general Lactobacillus ferment ingredients within a formulation may necessitate pH control and co-preservatives to ensure optimal preservation and stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Lactobacillus Ferment and its filtrates/lysates, including Lactobacillus Ferment Filtrate generally, safe for cosmetic use. Reported concentrations for Lactobacillus Ferment in face and neck products extend up to 5.6%. It is important to note that postbiotics derived from Lactobacillus bacteria have shown potential tyrosinase-inhibiting effects in some studies, which could theoretically influence skin pigmentation.
