How about instead of doing all this fancy surgery stuff to fake facial forward growth (LE ANTEFACE MEME) somebody was to artificially reduce facial forward projection by removing bone (in nose and eye area) and then inject himself with copious amounts of HGH to make his face grow by itself into its mature state, but this time with more harmonous proportions.
Now bare with me here, I'm at least 50% serious. Is there any situation where that could potentially make sense? For example in a person who at some point in the past or his entire past life was naturally deficient in HGH anyway? Like, i'm always open for new ideas (and so should you!), and maybe the simplest solution is the best and this is an option we aren't seeing.
