I just watched a video of that process, it’s really incredible. I don’t know much about how the skin works, does the dermis just regrow under the epidermis? I imagine it sort of repairs inwards from the edges of the wound using the epidermis as support, is that correct?

I’m really glad people like you are doing out there. I imagine you get used to it, but I feel squeamish just looking at the graft, not to mention the injury that required it!
