I need to organize my pore blackhead management routineㅠㅠ

I'm trying to manage my pores and blackheads, and I'm trying to do it as naturally as possible. I use a herbal skin toner and a clear gel without white cast. It seemed to be effective, but they keep coming back.

Even after washing my face, I still have problems. I wonder if it's because of the water temperature. Anyway, I have a lot of concerns.

Would it be better to change it to warm water?

I'm in a really difficult situation because I have to turn off the water in the sink where I wash my face at home so that the warm water doesn't come out.

Should I use a hose?... ㅠㅠ

What should I do...ㅠㅠ
