I am not quite sure if this would work. Yes, it's all about "heal to how you see yourself", but it could be a bit more demanding than that. I think it may well be the case that the "healing" is a necessary component of the whole process: you can't "heal" your face into looking different if it isn't damaged in any real sense beyond not looking a certain way. It's the difference between healing back a finger and growing an extra one, to some extent.
Recall also that Cognitive aspects also incorporate how others see you, to some extent.
Returned can mess with their appearance within a certain range, btw.
