I haven't been able to use chemical exfoliants for my skin lately, so I purchased this konjac cleansing sponge for a gentler approach to exfoliating my skin. It works perfectly! My skin is smoother after using it with my second cleanser. I run it under the shower head for a bit until it puffs up and it doesn't feel any hardness in the middle. The sponge goes back to becoming hard once it's dried. It comes with a string attached to it so you're able to hang it in your shower/bath.
