Is it okay to wash your face with cold water to tighten pores?

I'm worried because my pores seem to be getting bigger these days. I've heard that it's good to finish washing your face with cold water, and that it makes your pores smaller, so I've been doing that.

I don't know if this will work

Some people say that once pores are enlarged, they don't get smaller.

Is that really true? I have many thoughts.

I don't have oily skin, so I didn't really care about my pores ~ but I guess I can't help it because of my age ㅜ

Or maybe I should consider a procedure to reduce pores ~ I'll have to look up some reviews.

Every time I look in the mirror, I sigh deeply.
