I think I figured out part of why the word "ghoulish" kept coming to mind.
When the face is full of filler, the eyes become sunken in.
Just like a ghoul from fallout.
And then they all have small noses. And these too will sink in.
So ghoul.
The thing is, it's almost impossible to have that filler removed. Plus it has stretched the skin. So removing it would make their face look like how the skin looks in an area of extreme weight loss. That's kinda whatever on people who have lost weight/had babies , It is what it is.
But This will really mess up the face. It's not natural.
The alternative is to keep adding more filler until the face is 5x thicker and the eyes are so far sunk behind bags of filled flesh that they look black and demonic.
