Loofah is a natural vine fruit, harvested before maturity it is eaten as a vegetable (squash). The ripe, dried fruit is the source of the loofah sponge. The exfoliating action of loofah is used to help stimulate the lymphatic system, encouraging detoxification while stimulating blood circulation and skin cell renewal. This is known to help control the appearance of wrinkles and cellulite for younger, fresher looking skin. To keep a natural loofah sponge in good condition rinse thoroughly after each use and leave to dry in a ventilated place.
