Science
Mechanism of Action
This extract primarily functions through its high mucilage content, composed of polysaccharides, which acts as a potent natural humectant. It effectively draws and retains moisture in the skin, simultaneously creating a protective film that diminishes transepidermal water loss (TEWL) and defends against external stressors. Beyond hydration, it possesses anti-inflammatory capabilities to alleviate redness, swelling, and discomfort, alongside antioxidant activity that neutralizes free radicals and mitigates UVA-induced oxidative damage. The extract further supports skin health by helping to preserve natural hyaluronic acid levels and promoting repair, regeneration, and enhanced elasticity, while also demonstrating antimicrobial action against specific gram-positive bacteria.
