This product is an exfoliation tool-not really a facial exfoliator but I couldn't decide what category to put it in. Essentially, it's a flat blade with a curved handle that you drag against your skin to 'exfoliate.' Does it work? Well yes....for me, it is especially helpful in removing ingrown hairs. I find that if I use it before shaving, I end up with a closer, smoother shave (yay). As a scrub person, it was a bit difficult to get used to not having the gritty scrub on my legs but I like less mess. I don't use this under my arms but apparently you can use it anywhere on your body!
