Science

This extract actively enhances skin repair by upregulating genes involved in collagen synthesis. Its astringent qualities gently contract skin tissues and contribute to hemostasis, while a cooling effect calms pain receptors, particularly useful for burns. It exhibits anti-inflammatory action to diminish irritation and redness. Phormium Tenax Extract supports the healing of compromised skin, enriched by linoleic acid that fortifies the skin barrier and retains moisture. The mucilaginous sap, rich in polysaccharides, provides humectant and emollient effects, boosting hydration. It also promotes healthy cell turnover, manages inflammation, and offers mild antimicrobial activity against spot-causing bacteria. Key active compounds like D-xylose act as humectants, and D-glucuronic acid helps balance pH, further contributing to its soothing and protective profile alongside antioxidants, flavonoids, and natural sugars.
