I used my alum block tonight to mainly seal a few cuts that were bleeding and flowed dark red (must have lost iron stores here). It was not my new straight that caused this but my DE as last night I rinsed it out but forgot to the screw the blade up tight again, tried to square up my side burns after my straight shave and managed instead to scrape a series slice marks 3 cm downwards.

I put the alum block directly on the cuts and held it there for a minute or so (a cold towel did not work) and the residue alum was running streams down my freshly straight razor shave, I almost went through the roof as if been stung by a 1000 wasps but the alum stopped the bleeding and sealed up the cuts fast.

Alum is basically the only product I can put on my face that does not cause acne 12-24 hours later, excellent stuff but it sure does bite if your skin is open with cuts or razor abrasions.
