Science
Mechanism of Action
This ingredient employs a synergistic mechanism, combining the inherent properties of Sasa Quelpaertensis with the bio-enhancing effects of Lactobacillus fermentation. Sasa Quelpaertensis, rich in flavonoids and vitamins, delivers significant antioxidant protection against environmental stressors, while simultaneously soothing the skin, reducing redness, and alleviating irritation. It actively contributes to restoring skin comfort, strengthening its protective barrier, and promoting deep moisturization and cellular regeneration, especially beneficial for sensitive complexions. The Lactobacillus fermentation process yields an array of postbiotic compounds that exhibit probiotic-like effects, anti-aging potential, anti-microbial, and anti-inflammatory actions. These postbiotics support the skin's natural microflora balance, stimulate beta-defensins in skin cells, and enhance oxygen uptake, collagen production, and ATP synthesis. The fermentation itself plays a critical role by increasing the bioavailability of beneficial compounds, potentially reducing molecular weight for improved skin absorption, and creating novel or intensified pharmacological effects. The combined fermented extract has demonstrated efficacy in improving the appearance of wrinkles, enhancing hydration, fortifying the skin barrier, providing a brightening effect, and augmenting overall antioxidant capacity.

Conflicts
- Formulation must carefully consider the potential for postbiotics from Lactobacillus fermentation to act as tyrosinase-inhibitors, which could lead to unintended skin depigmentation. Products should be designed to avoid this effect if brightening is not the primary goal or if a specific skin tone is targeted.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Lactobacillus Ferment and related filtrates/lysates, a group encompassing components of this ingredient, are safe for use in cosmetic applications. The highest reported concentration for Lactobacillus Ferment in face and neck products is up to 5.6%. Formulators should be cognizant of the potential for Lactobacillus fermentation postbiotics to inhibit tyrosinase, which could result in unintended skin depigmentation. Therefore, the ingredient should be used in a manner that precludes this outcome. While unfermented Sasa Quelpaertensis extract is generally regarded as safe, a preliminary skin test is advisable for individuals with particularly sensitive skin or known allergies. Inhalation toxicity data for general Lactobacillus Ferment ingredients were not available during evaluation.
