I'm positive that sagging jowls is from some
sort of nerve damage & or B vitamin deficiency,
aka, once the nerves start dieing that the tension
in your face gets lost, that lack of supportive nerves
is why the jowls sag,
I think I see this in my face, btw I've got really
bad nerve damage from colozapine,
lack of healthy nerves in your face conduits
the sagging jowls,
