LACTOBACILLUS/CUDRANIA TRICUSPIDATA BARK EXTRACT FERMENT FILTRATE.

This ingredient exerts its effects through a dual-pronged mechanism. Lactobacillus fermentation produces a rich filtrate containing beneficial metabolites, enzymes, and peptides that bolster the skin's natural barrier, support a stable skin microbiome, and act as humectants to significantly improve hydration. These ferment byproducts also exhibit potent antioxidant activity, helping to neutralize free radicals and balance skin pH. Notably, certain Lactobacillus metabolites can inhibit tyrosinase, which contributes to reducing hyperpigmentation and enhancing skin brightness. Concurrently, Cudrania tricuspidata bark delivers key phytochemicals like xanthones and flavonoids, known for their anti-inflammatory and antioxidative properties. Research indicates that compounds from Cudrania tricuspidata can decrease pro-inflammatory markers such as IL-6 and IL-8 production and inhibit NF-κB translocation in human keratinocytes, providing targeted soothing and protective action at a cellular level. The combined effect functions comprehensively as an antioxidant and skin conditioning agent.
