Small-Scale Question Sunday for October 16, 2022

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Is there a scientific best care regimen for scrapes/wounds? I got an annoying scrape on my knee while drunk last week and I've pretty much left it alone. The scab gets loosened up by showers then tightens up and pulls on the skin near it, and direct pressure on the wound is currently uncomfortable but managable. Is there a literature on what makes scrapes heal faster or not? Is there a point in applying and reapplying a bandaid past the point where it has stopped bleeding?

As a follow up to this question, considering how long some wounds takes to heal after 30+ is there a helpful solution to calm myself and not to try and scratch it every other day? Stupid ingrown hairs.....
