Let me start by saying this glove is no joke. The first time I used it in the shower, I was shocked by how much dead skin came off - like little gray rolls that I could actually see washing down the drain. It's satisfying in a weirdly gross way that makes you want to keep scrubbing.
I have keratosis pilaris (those annoying bumps) on my arms, and after about 3 uses spaced a week apart, my skin is noticeably smoother. The texture isn't sandpaper-level rough but has just enough abrasiveness where you can feel it working without hurting sensitive areas.
Pro tip: Soak your skin for 5+ minutes first - I sit in a warm bath or let shower steam do the work. Dry scrubbing does nothing. Also go gentle on bony areas like knees; this thing means business.
The mitt lost some roughness after 6 uses, so I'm ordering replacements (they recommend changing every few weeks). Worth it though - my self-tanner applies way more evenly now without patchiness. Just don't use right before tanning like I did once - hello streaky disaster!
It's not magic for feet calluses (I still need a pumice stone) but amazing everywhere else. My husband stole mine for his back acne and now we're fighting over who gets to use it on Sundays.
