Can doctor's fuse new skin into a scar without an open wound site. This is for an accident over 3 years ago.

They’d have to make sure of a good blood supply so might have to scrape away some scar tissue as it has no blood supply. Sounds like the blood is right there if it’s ripping open. there is also a techique where a graft remains partly attached to it’s donor site while it grows onto the new site, the trimmed up. Where is your scar?

How does the epidermis grow multiple layers if it’s working off the blood supply…meaning if the blood supply only touches the first or second layer of epidermis, how do the other 5 layers still grow. There must be a “fusion” ingredient somewhere in nature that would act as a sort of welding, or combining material to put new skin on top of to integrate seemlessly. The accident was in a sensitive area.

The epidermis grows because of hundreds of tiny capillaries. Google new medical discoveries in skin grafting. I don’t see how it could work like real skin without being real skin especially in a sensitive area But new discoveries everyday. What does your doctor say?

They do have a technique where they can take skin from other parts of your body to help cover the thin layer, but I still don’t see how it could grow multiple layers.
