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?
If the scar is new, massaging it frequently (using some type of serum or oil to reduce friction) can help reduce the size and how much it is raised.
If it’s more than a year post-injury, only a plastic surgeon could help.
