Loofah - a natural material, not synthetic, for the three years that I use it, it does not lose its properties, on the contrary nice little softened. With the habit it may seem harsh, but it is well exfoliates the skin, is very good for anti-cellulite massage and I love it and use it just for the soul. After her, remembering something shapeless synthetic feeble, now I understand that the usual little sponges cleanse the skin, and certainly do not provide a pleasant and gentle massage that is very important for me, it provides a really high quality lymphatic drainage effect for the feet and body! After the sponge loofah, I do not take no more than a sponge, and recall them with a shudder. It is a thing !!! I recommend heartily to try what real quality! I would be glad if my review useful to you!
