Science
Mechanism of Action
This extract works by inhibiting 5-α reductase type 1 expression, directly leading to a reduction in sebum activity and squalene production. This targeted action effectively diminishes the appearance of oiliness and minimizes pore size. Beyond sebum control, it offers robust moisturizing capabilities, reinforces the skin's natural barrier, and exhibits strong antioxidant properties to shield against environmental aggressors. Its anti-inflammatory effects help soothe and calm sensitive skin, while also contributing to improved skin elasticity and a reduction in visible signs of aging.
