The exfoliator is made from the fibrous root of the Konjac plant. It is enriched with detoxifying kaolin clay. The sponge is also biodegradable and compostable. It is recommended for all skin types. The soft sponge can be used by itself or with a cleanser to leave skin feeling smooth and soft. My skin felt great after the sponge. It removed my mascara without much effort although I did lose a couple of eyelashes.
