It has been about a month since I started pore care. Is it normal for changes to appear this slowly?

Hi haha. Recently, I've wanted to improve my skin condition, so I've started serious pore care. I used to think that just washing my face well was enough, but at some point, the pores around my nose and cheeks started becoming noticeable. It was stressful because they stood out even more, especially when I looked in the mirror or took photos in the sunlight.

So I bought some new pore care products and changed my cleansing habits a bit, but I haven't really noticed any significant changes yet, haha. My skin texture feels a little smoother, but my pores don't seem to have changed much, so I became curious.

Is it normal for pore care to take a long time? Some people say their pores improved in just a few weeks, while others say you need to manage them consistently for several months or more to see results. So I'm wondering if I'm being too impatient.

Also, while doing pore care, I tend to add various products, but I am concerned because I heard that using too many products is not good. I am wondering if it is right to just consistently do the basic care I am doing now, or if I need additional care.

If anyone has experienced satisfactory changes from consistently doing pore care, please let me know how long it took. I would like to hear your experiences so that I can continue managing my care without giving up. When did you first notice the effects of your pore care?
