I have no idea, Nelson.
Sometimes I wonder about all those products we can put on after a shave. Most of them, I simply use because they are a nice treat, or because my wife likes the scent. I tell myself my skin might benefit on the long term, but as far as an instant remedy goes for the (rare) occasions that I just can't call it a day and keep on shaving till my face burns, I haven't found anything that really made a difference yet.

I always do the cold water rinse and run the allum block over my wet face. Then I clean up before rinsing the dried allum away and putting on someting else (if I put something on at all). Of course the "3 minute" window being long passed by then.

I wonder what others will answer to your question.

best regards,
Bart.
