Science
Mechanism of Action
This extract functions as a multi-modal agent within the skin. It acts as a humectant and emollient to enhance skin hydration and smoothness, while also providing a protective barrier. Its rich content of bibenzyls and other constituents confers antioxidant benefits, neutralizing free radicals, and exhibits anti-inflammatory effects. Additionally, it has demonstrated inhibitory activity against tyrosinase, an enzyme crucial for melanin synthesis, suggesting a role in addressing hyperpigmentation.
