Science

Mechanism of Action

Its unique biochemical composition closely resembles human sebum, allowing it to integrate seamlessly with the skin's natural hydrolipidic film. The butter acts as an intensive emollient, strengthening the epidermal barrier and reducing transepidermal water loss to combat dehydration. It further contributes to skin health by regulating sebum, enhancing elasticity, and delivering antioxidant protection through its natural tocopherols, thus restoring the skin's inherent protective layer.
