(gross but serious) How should I deal with these boogers?

I had a cold a couple weeks ago. I have since recovered but since then, my nostrils keep getting clogged up with boogers. It wasn’t like this before the cold. I tried removing the boogers when I wash my face but somehow they keep returning. Most of the boogers are dried and tend to cling to the edge of my nostrils.

Should I continue removing the boogers? I am afraid that I would create scar tissue in my nose. However, it is very hard to breathe without the boogers removed. So, is there a better way (medicine, home remedies) for me to clear the boogers once and for all without damaging my nose? Or is patience the best way to go?
