Use sharp razors and learn the right technique, it's going to stop the continuous assault on your skin! Next, make sure you use good soap or cream with good lather. There are some good materials on that. Finally, my personal favorite: Get an alum block. After shaving, use cold water and wipe it across the face. It may sting and tingle, but it works well for many different skins and the tingle/sting/burn is a good learning tool when it comes to indicating flaws in the shaving.
