Concerns about pores~ Would finishing my face wash with cold water be helpful?

If you finish washing your face with cold water...

I usually finish with cold water... but some people

I've heard some people say that cold water is bad because it irritates the skin. I really hear all sorts of things. I've also heard that lukewarm water is better.

I'd like to believe that.
