The best option is to exfoliate your skin using a natural sponge. These sponges are organic, effective and very beneficial for the skin. The most commonly used sponge is one that comes from the luffa - or loofah -, a plant from the same family as the cucumber. The woven fibers of the sponge gently massage the skin and stimulate blood flow. It detoxifies and encourages skin renewal while leaving your skin extremely clean and refreshed.
