No matter how much I take care of it, these damn blackheads keep appearing.

I am stressed because I have so many blackheads on my nose. In the past, I only saw a few on the tip of my nose, but lately, black dots have appeared densely all the way around the sides of my nostrils. When viewed up close, it looks like sebum is stuck in every pore, making my skin look messy overall.

I've tried using cleansing oil and even nose strips occasionally, but the relief is only temporary, and it returns to normal after a few days. I'm trying my best to hold back because I feel like squeezing it with my hands will make it worse, but seeing it keeps bothering me.

I am curious whether blackheads are caused by excessive sebum production or if they become more visible due to enlarged pores. Are there any separate procedures available at dermatology clinics to manage blackheads other than extraction? I would also like to know if I need to receive treatments to reduce sebum and improve pores together. I would appreciate it if clinic staff could answer whether consistent care can delay the recurrence of blackheads.
