I have heard reviews and wonderful things about Smooth Away. So I tried it. It does work BUT it takes a bit more effort than just shaving. It would work better on finer hair than course. It did not leave red marks on me and seems to last a bit. It was not painful, though it is like sandpaper. It is really, really soft sand paper.
I am not sure that I will continue to use this product. I needed 2 pads to get both legs done. I think that seems a bit expensive. If you need to shave and have no water that you can use this product is great!
