The tip of my chin sticks out a little and my chin is large, but I don't have a malocclusion or a protruding chin. However, even though I'm 20 years old, the side of my nose is sunken (the philtrum seems to be sunken as well), so compared to my friends, my nasolabial folds are very deep and my face is strangely very flat.. Let's look at the nasolabial fold in any lighting. I'm so jealous of my friends who don't have facial features and have smooth faces. To what extent can the things I mentioned above be improved with double jaw? I've thought a lot about beauty orthodontic treatment because my arms and flat face are really, really stressful. Please don't tell me not to do it.
