I was trained not to go over the same area twice with warm wax especially on the face, you may get away with it on legs but that is depending on how sensitive a clients skin is. I have to say I have never looked back since using hot wax on eyebrows, I was almost ready to give up with eyebrow waxing because of the same clients always looking like skin was removed and that was only waxing over the area once - all my clients have been impressed with the hot wax, they say it is less painful and they do not go as red and as I said before I have never ever caused a graze with hot wax x
