How should I manage my pore care cycle?

I had been stressed for a long time about excess sebum and blackheads around my nose, so I recently started pore care. I used to think that just washing my face thoroughly would be enough, but as time went on, my pores looked even more prominent. So, I tried getting pore care at a dermatology clinic, and I definitely felt that my skin texture improved compared to managing it on my own at home. I was most satisfied with the reduction in makeup settling around my nose. However, since pore care isn't something you get done in a single session, I'm wondering how often I should get treatments. I'm worried that getting it too often might irritate my skin, so I would appreciate any tips on treatment frequency from those who have consistently received pore care.
