I got really tired of cutting up my legs with razors and razor burn.I do have sensitive skin to razors.I personally find that nair though it tingles does do a wonderful job on my legs.
I would never ever recommend putting this product on anything but legs from the tingling sensations alone.It does have a very loud stench as well even though they try to have different fragrances of this product.
I think everyones bodies react differently under similar circumstances.To me it works.
