If I have a very thin piece of scar tissue on my skin, and then I surgically cut the skin open right along the middle of the scar, and ensure that I do all the best scar healing practises (like holding the skin on either side of the wound together), what will happen? Will the scar get smaller or bigger?
I would place a bet on “makes it worse” right now.
Dermatologists have some kind of magic shot that makes them go away. The top of my shoulder was covered in a nasty, lumpy scar from a childhood injury. After 2 rounds of shots and a few years time, you can only tell it was there because it tans different than the surrounding skin.
