Science

Mechanism of Action

This botanical extract demonstrates multifaceted efficacy by directly stimulating the production of collagen and pro-collagen, fundamental proteins for skin structure and elasticity, while also increasing epidermal thickness for improved skin barrier function. It further enhances skin plumpness and minimizes the appearance of sagging by stimulating lipid production (lipogenesis). Rich in antioxidant compounds, particularly flavonoids, it actively neutralizes free radicals, thereby protecting skin from environmental damage and premature aging. Its anti-inflammatory properties effectively calm and soothe skin, making it beneficial for various sensitivities. Additionally, it functions as a natural humectant, attracting and retaining moisture, and an emollient, softening the skin's surface. Preliminary data suggests potential in brightening skin tone through melanin inhibition and providing antibacterial benefits.
