And while there’s not a whole lot that can be done for scars that are already there, researchers have figured out how to make fresh wounds heal as normal, regenerated skin, instead of the usual scar tissue – something that was previously thought to be impossible in mammals.
“Essentially, we can manipulate wound healing so that it leads to skin regeneration rather than scarring,” said one of the team, George Cotsarelis, chair of the Department of Dermatology at the University of Pennsylvania.
“The secret is to regenerate hair follicles first. After that, the fat will regenerate in response to the signals from those follicles.”
