Science
Mechanism of Action
This extract exerts its benefits primarily through a rich concentration of flavonoids, including rutin, quercetin, and genistein. These compounds provide significant antioxidant protection against free radicals and UV damage, while also demonstrating anti-inflammatory capabilities that reduce redness and soothe conditions like eczema. The extract promotes a more even and luminous skin tone by inhibiting melanin production, enhances skin elasticity and reduces wrinkle appearance by stimulating collagen synthesis, and strengthens the skin's natural barrier through optimized keratinocyte differentiation. Furthermore, it acts as an emollient, delivering essential nutrients and maintaining overall skin health.
