The luffa is a plant of tropical origin that is cultivated in Spain in an artisanal way thanks to an agroforestry project to revitalize the natural cultivation of loofah. This plant is cut and molded to make natural sponges and sponges. Thanks to the roughness of the luffa, the sponges have exfoliating properties for the skin.
When in contact with water, these sponges release cucurbitacin, a substance that provides hydration, which is why when they get wet they increase their size three or four times.
