It does what it says it does. Seeing and feeling all the dead skin sloughing off is pretty gross, and my skin is beautifully soft afterwards. If you have very sensitive skin, test this out on your leg before going to town on the rest of your body. For me it feels satisfying, like scratching an itch I didn't know I had.The instructions are minimal so I did have to do a little research to make sure I was using them correctly. Just like any other scrubby exfoliator, using it every day will irritate your skin. It's easy to use in the shower or bath after your skin has had time to soak/soften, and it works best when both skin and towel are damp and not dripping wet. For maximum effectiveness, apply a good moisturizer while your skin is still a little damp.It'll appear to shrink a lot after washing, but it will stretch back out when you put your hand in. It's machine washable but it needs to be air dried. One of mine accidentally got mixed in with the regular laundry, and though it was still all in one piece afterward, my lint trap had a LOT of green powder in it that I assume is a result of the towel being exposed to harsh heat/tumbling.
