ELI5: If a vitamin C deficiency can cause old scars to re-open, why can't this be used to heal/remove scars?

I've heard multiple times that scurvy or vitamin C deficincy can cause old scars to open again, can this be used in a controlled way to remove scars?

For example, if someone had a bad facial scar that they wanted removed, couldn't a doctor monitor vitamin C levels until the scar reopens and then treat the injury?

There’s no localized vitamin C deficiency. So if you intentionally cause scurvy, your whole body would experience issues with collagen synthesis, your teeth would start falling out, your joints will hurt, etc etc etc. Probably not worth it to fix a scar…
