I would have thought that "flesh" is either muscular tissue or similar tissue, rather than skin, making "fleshless skin" unclear. There are various parts of the body where the skin is just above the bone, such as ankle, knee, backs of fingers, elbow, scalp, etc., and also areas where the skin is rather thin and easily lifted, such as the inside of the wrist. However, I fail to see why there would be a significant association with bleeding, which must relate significantly to the blood vessels that are damaged. I referred to the scalp, not the entire head.
