Konjac Sponge Enhance your skincare routine with the Konjac Sponge. Made from a porous root vegetable grown in Korea, the Konjac Sponge is perfect for delicate skin. This 100% preservative free sponge gently exfoliates by sweeping away dead skin cells and unclogging pores. It’s great to use along with our Rhassoul Clay Face Bar or Activated Charcoal Face Bar. Hang your sponge from the attached string for quicker drying.
