Whenever I am done shaving, I pass my alum bar all over my face and then wait for a couple of minutes before taking a shower. While it does sting a little (or a lot, when I first tried my new R41), it is very bearable. The problem is that, by the time I am done showering, my lower neck shows a fair amount of irritation, with a few patches of skin visibly reddish. Is this normal and expected? Does it mean that I am applying too much pressure to those areas that become irritated? Could it be an allergic reaction to the alum bar itself? I don't ever get this irritation if I don't use the alum bar. I usually apply a layer of Proraso Pre & Post Shave Cream after the shower and by the time I wake up (I shave before bed), the irritation is gone.
