I used to rub this lightly on my face every time I shaved after applying the cold water, both to stop bleeding and as an antiseptic on my face. Nowadays, I rarely ever nick myself anymore (hope this doesn't jinx it), so I stopped using it and I find I'm having a much more comfortable after-shave experience.

I think the alum sticks around on my skin and stings me all day (i.e. when my sweat re-activates it). Does anyone use alum regularly, and what kind of results do you get with it?
