I use an Alum Block after each shave, but not on the entire face. I use it mainly underneath the jaws, under and on the chin as well as the throat sometimes (depending on how awake i was when shaving...) After applying it, I leave it for about 15-20 minutes and then apply my regular aftershave lotion or tonic, depending on my mood. I have a couple of times only used the Alum block, but it does get a bit uncomfortable later in the morning..
