100 percent works if used properly
I was a skeptic but these sponges work really well. I washed like normal and then just stood in the shower stream for a while to “soak”. Got the sponge wet and wrung it out and then wiped off my arm and started gently scrubbing with the sponge. Sure enough, little piles of skin were all over me! I also used it on my face and got a good amount off there too- it feels so smooth! The sponge feels just like a magic eraser except more sturdy. I made my super-dry-skinned kid soak in the tub for 15 minutes and then scrubbed his arms and legs and I was amazed at how much came off of him. He was pretty grossed out and said I ruined his bath water because of all the skin.  So what I found out is the longer you soak, the better it works. Use it on cleaned skin, no soap, and maybe even wipe off excess water first. The packaging is all in a language I don’t speak so I’m basing this advice on what I’ve read elsewhere and my personal experience today.
