Dr. Sponge is made from an amazing and unique material that is soft, natural, and even a food-grade Konjac plant-fiber. Konjac is an exotic native plant of Eastern Asia. It has been used in Asian food and medicine as a result of its natural nutrients being rich in vitamins A, E, D, B1, B2, B6, B12, and C, as well as minerals. This Southern California-based company has brilliantly infused these cleaning sponges with other healthy additives to benefit a variety of issues that will cater to many skin types. You'll want to replace any old wash cloth or loofa you might have been using. The benefits will be seen in the results of your glowing skin that has been gently exfoliated, cleaning pores, removing dirt and oil, and balancing the skin's acidity and pH balance. These sponges leave your skin feeling clean and moisturized without leaving any residue.
