LACTOBACILLUS/(ANGELICA ACUTILOBA/CNIDIUM OFFICINALE/GLYCYRRHIZA GLABRA/PAEONIA ALBIFLORA) ROOT/ SCHISANDRA CHINENSIS FRUIT FERMENT EXTRACT FILTRATE.

The mechanism of action for this ingredient is a synergistic integration of microbial fermentation and botanical bioactivity. Lactobacillus fermentation confers natural antimicrobial properties by acidifying the skin environment and producing bacteriocins, which supports a balanced skin microbiome and provides sustained moisturization. Angelica Acutiloba root extract exhibits antioxidant activity, stimulates type I procollagen synthesis, and demonstrably reduces MMP-1 expression and MMP-2 activity, suggesting potent anti-aging and wrinkle-reducing effects. Glycyrrhiza Glabra (Licorice) root extract contributes significant depigmenting, anti-inflammatory, and antioxidant benefits, with its key compound glabridin inhibiting melanogenesis by suppressing CREB/CRTC1-mediated transcriptional activation of MITF. Schisandra Chinensis fruit extract is rich in antioxidants and offers anti-inflammatory action by decreasing pro-inflammatory cytokines such as TNF-α, IL-1β, IL-4, IL-6, IL-8, MCP-1, and TSLP, while also aiding in the restoration of skin barrier function. Collectively, this complex ingredient works to condition the skin, reduce inflammation, combat oxidative stress, soothe irritation, address signs of aging, and may contribute to brightening and sebum regulation.
