Science
Mechanism of Action
This sophisticated ferment functions through multiple pathways to enhance skin health. Primarily, it acts as a powerful humectant, drawing and binding moisture to the skin via its inherent water-binding compounds, thereby ensuring optimal hydration and preventing transepidermal water loss. Its rich profile of polyphenols, amino acids, and vitamins (C, E) provides potent antioxidant defense against environmental stressors and free radical damage, further bolstered by piscidic acid, an iron chelator that inhibits free radical formation. The extract exhibits soothing and anti-inflammatory properties, clinically demonstrated to reduce irritation and redness by modulating stress markers. Furthermore, its fermentation process yields gluconic acid, a Polyhydroxy Acid (PHA), facilitating gentle exfoliation to accelerate skin cell turnover. This action, combined with its capacity to boost collagen synthesis, leads to improved skin elasticity, firmness, and a reduction in fine lines, while simultaneously restoring and strengthening the skin's natural barrier function.

Key findings
- 01 At concentrations of 0.01%, 0.1%, and 1.0%, this ingredient dose-dependently enhanced keratinocyte intracellular calcium levels by 5%, 8%, and 20% respectively, correlating with increased collagen synthesis.
- 02 Clinical evaluations demonstrated a 46% increase in collagen synthesis in fibroblasts when treated with 0.01% and 0.1% concentrations, compared to untreated controls.
- 03 Application at 5% concentration resulted in a significant 320% increase in cumulative cellular renewal when measured against a standard base lotion.
- 04 Trials confirmed soothing efficacy against skin irritation induced by UV exposure or wet shaving, alongside a sustained moisturizing effect.
