I don't know the science that deeply behind the "pores" but what my barber tells me is that when you warm up the skin the hair relaxes and extends so you will have more of it above the skin to cut vs when at a colder temp and you get a "closer" shave that lasts longer. Experience seems to confirm this and that is why I switched to the shower also because I was cutting myself more than I liked to get the shave quality I wanted. But when I was in the shower it was such a pain in the butt to lather that I ditched it.Just one minor correction @Attilio, a person's skin does not have any pores that open and close (due to heat/cold or any other external action). This opening/closing of pores in the skin is a myth put out by advertising agencies.
Other than the above, it is good to hear that you have found a shaving system that works for you.
From time to time I do try to use the products as they did cost a pretty penny and I want to make use of what I have left but then find that I lose sensibility on my face with either oil or the cream and then I cut myself WAY more. Even lathering soap does that. I do it all by feel. I use DE razor if I don't push at least somewhat, and more than what is recommended, I don't get a close shave. Tried using a sharper razor or bigger gap and shaving gently and in that case it doesn't cut but it still slices up my face. I just have to know where and when to push tactically and without product helps me feel that.Whenever I DE shave,
it's in the shower using whatever soap happens to be there.
A soaped up face won't dry out in there.
Shaving in the shower without a mirror
requires the same level of skill
as touching your nose with your eyes closed.
If a cop pulls you over and
you're unable to touch your nose with your eyes closed,
you ain't driving home.
FYI I am alcohol free if that's any help new studies of the last 10 years show there's no safe dose and in concert with how much money behind alcohol there is and the voice is overwhelmingly anti, I listen. Quit years ago don't miss it at all. Would willingly submit to chemical testing instead can pass 100% of the time accordingly.
