Can blackheads and enlarged pores be improved with self-care?

I've been trying home care because of the blackheads that have formed around my nose and the pores that are getting bigger, but it doesn't seem to make any difference.

I'm going to try the pore care routine recommended by Maypure because I heard that irritating nose packs actually make pores bigger.

Has anyone seen any success in shrinking pores or removing blackheads through consistent cleansing at home? I'm curious whether emulsifying with cleansing oil is better, or whether regular exfoliation is more important.

If you have any home care tips that have actually worked for you to get rid of blackheads and tighten pores, please share them with us!
