TRITICUM VULGARE/AESTIVUM GRAIN EXTRACT.

This extract operates through multiple synergistic pathways to improve skin health. Its high content of phytoceramides, crucial plant-derived lipids, strengthens the skin's natural barrier function, effectively preventing moisture loss and ensuring optimal hydration, which concurrently smooths and reduces the appearance of wrinkles. As a potent antioxidant, it scavenges free radicals generated by environmental stressors, thereby mitigating visible signs of aging, brightening the complexion, and stimulating vital collagen synthesis. The extract acts as both an emollient and a humectant; it forms a protective film on the skin surface, shielding it from external irritants, while also binding water molecules to provide deep conditioning and sustained moisture, leading to a softer and healthier skin texture. Furthermore, it actively promotes keratinocyte healing and tissue repair by modulating the expression of metalloproteases (MMP-2, MMP-9) and upregulating key structural proteins such as collagen I and elastin, alongside integrin αV and aquaporin 3. It exhibits mitogenic and proliferative effects on fibroblasts and keratinocytes, enhancing overall tissue regeneration. Its anti-inflammatory capabilities are demonstrated by its reduction of pro-inflammatory markers like IL-6, TNFα, prostaglandin E2, and nitric oxide, coupled with an inhibition of NF-kB activation. The extract also induces fibronectin expression, increases hyaluronan synthesis, stimulates actin polymerization, and aids in the restoration of the epidermal barrier through enhanced lipid synthesis, ultimately improving skin elasticity and texture.
