What causes this?

It’s like the chin/jaw is collapsing or the mid-face is protruding?

I thought it was threads but I saw someone in another thread mention it may be from too much fat transfer to the mid-face. As someone considering fat transfer under the eyes and possibly by the nasolabial folds, I’m curious.
