I don't use an alum block. Styptic pen for weepers and nicks, and a good alcohol based aftershave will give me all the "feedback" I need about the quality of my shave. And I'm gonna use that anyway.

A loud scream would always follow the alum block being swiped over the cold sore.
The concern is accumulated Al over time.My mom used to make us put powered alum from the spice cabinet on those little ulcers you get after eating acidic foods. Wet a q-tip, dip in the alum, and rub it on the ulcer. It hurt, and tasted, like hell but it seemed to work... And I'm still alive today 40 years later
I had a roommate who used to use alum blocks for cold sores in his mouth. A loud scream would always follow the alum block being swiped over the cold sore, but he said it always worked to get rid of them.
