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?
When I was 14 I had a 2-3mm scar on my forearm. I didn’t like how it looked, so I took some toenail clippers and clipped off the scar tissue. Now I have a 4-5mm scar. I can’t believe I did it, and thinking about it now makes me cringe. But there’s a data point for you.
