Science
Mechanism of Action
This complex ingredient operates through multiple pathways to enhance skin vitality. Its fermented components from Lactobacillus, Saccharomyces, and Rice Bran act as potent antioxidants, effectively neutralizing oxygen-promoted reactions and preventing cellular damage. They contribute significantly to skin conditioning, moisturization, and emolliency by boosting hyaluronic acid levels and aquaporin 3 expression, thereby strengthening the skin barrier function. Specific actions include inhibiting melanin synthesis for a brighter complexion, promoting procollagen synthesis to mitigate signs of aging and wrinkles, and reducing inflammatory responses, particularly against UV radiation. The inclusion of Sophora Japonica Root Extract, rich in protective flavonoids like quercetin, further augments these effects by providing additional antioxidant and anti-inflammatory support, improving capillary resistance, and assisting Vitamin C in maintaining collagen health.

Key findings
- 01 A 5% Saccharomyces boulardii fermented product filtrate demonstrated significant efficacy in repairing damaged skin barriers, leading to an average 37.2% reduction in trans-epidermal water loss (TEWL) and a 62.5% increase in stratum corneum hydration over four weeks.
- 02 An alcohol-free rice bran fermentation solution, especially at a 20% dilution, exhibited anti-aging effects, inhibited melanin synthesis (achieving a 9.29% improvement rate in whitening over 30 days), and provided notable moisturizing benefits (a 44.31% improvement rate).
- 03 A lotion formulated with 10% fermented black rice bran extract resulted in a significant reduction in hyperpigmentation among female subjects.
- 04 Saccharomyces/Rice Ferment Filtrate displayed strong in vitro antioxidant and anti-wrinkle activities, alongside clinically observed improvements in skin hydration and elasticity in vivo.

Safety
Safety Profile
While individual components such as Lactobacillus Ferment Ingredients and Yeast-Derived Ingredients (including Saccharomyces Ferment Filtrate) are considered safe for cosmetic use by the CIR Expert Panel (with a maximum reported concentration of 5.6% for Lactobacillus Ferment in certain leave-on products), the specific combination ingredient 'LACTOBACILLUS/SACCHAROMYCES/RICE BRAN EXTRACT/SOPHORA JAPONICA ROOT EXTRACT FERMENT FILTRATE' has not undergone a consolidated review by CIR, SCCS, or FDA. Its irritancy and comedogenicity are currently unknown.
