Science
Mechanism of Action
This extract acts as a potent antioxidant, utilizing its polyphenol content to defend skin cells from environmental damage. It delivers significant moisturizing benefits, improving hydration and supporting skin elasticity for a more supple feel. With soothing properties, it effectively reduces irritation and redness, while strengthening the skin's protective barrier against pollutants and moisture loss. Containing silica, a key component in skin formation, it may also stimulate collagen synthesis, promote balanced sebum production, and exert anti-inflammatory actions by inhibiting pro-inflammatory mediators. Furthermore, it demonstrates antibacterial efficacy against bacteria such as *Staphylococcus aureus* and exhibits melanin-biosynthesis-inhibiting and anti-allergic potential.
