a couple of years ago I wiped out when I went over the handlebar when I hit a nasty pothole. The back pack strap rubbed a couple of layers of skin off on my chest under the collarbone. I really didn't want a scar there (and I scar very easily).

I babied it like nothing else with tea tree oil to prevent infection, slathered on pure shea butter, then kept it under sterile gauze until it wasn't scabby anymore (about 10 days). It was much more comfortable without my skin shrinking, and in the end it didn't leave a scar.
