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 don’t have an answer for you, but something to consider.
Plastic surgeons go to school for many years to perfect their trade. I suspect, like most medical professionals, something like scar reduction is a specialized area of study that is not all that common.
We know that professionals are able to reduce the appearance of scars. I’d bet good money that it is not something just anyone could do successfully.
