Thread: Alum ?

I don't use it on myself, but have used it on animals if we cut their nails too short when trimming. Just put it on the area you are concerned about. If you want to use it all over you face, it makes sense to me to mix it with cornstarch. I'd start with 2 parts cornstarch to 1 part alum and adjust as seems appropriate.

Talc is bad for your lungs, so I wouldn't get it near the mouth or nose
