Alum block after shaving: Alzheimer's risk?

So I hear that aluminum is pretty bad for your body (and maybe is linked to Alzheimer's?). I also hear that alum (which is used to close nicks after shaving) is the name of an aluminum compound. The majority of info about alum crystals for personal hygiene tends to be on "natural living" web sites and the like, so my main question is: is there any actual scientific study either way as to the safety of such a thing being rubbed on your face on a regular basis?
