I have been looking at soap recipes and I am wondering about the safety of using lye. Reading that lye is destructive to living tissues, can cause burns, scars or blindness, etc. is rather scary. But the lye-free recipes call for commercially made soaps like fels-naphta that contain ingredients I would not want to use. And what is the point of making your own soap if you are making it with store bought soap? Does the lye change when combined with the fat that it is no longer harmful to skin?

I have never attempted to make soap before so I am completely ignorant on the subject. I would appreciate any advice.
