Yea these do work. I've tried them on my legs. I use the Hairoff one instead tho. It's more grainy so you have to be careful to not burn yourself while you are circling. IMO, it works faster then the SmoothAway. I found myself circling FOREVER with the SmoothAway. SmoothAway you can find in most drug stores like CVS, in Bed Bath and Beyond, "As Seen on Tv" stores, and i'm sure in many other places. I got the HairOff at Ulta.
