How can I improve facial alignment and contour? (Photo)

Hi luminous. If you are truly interested in that "influencer aesthetic", then yes, you can definitely do more filler, possibly buccal fat removal. I woudl be careful about the buccal fat removal because by doing this, you will be deflating the face somewhat meaning you would get more skin sag, which it sounds like you are worried about. It is possible that with enough filler, you can overcome this. You can definitely handle more filler in the lateral cheek bone region and posterior jawline if you want that "influencer look" based on how they all look.

Hello,
You may benefit from Botox to the masseters to allow the back / lower jaw area to “slim out.” This will help augment the results of your jaw filler also. Please see an experienced surgical injector for best results.

There isn’t a single person on this planet, who is facially symmetric. The only place where you can find someone with a symmetric face is in a wax museum and every single celebrity there looks extremely weird if not alien because of that symmetry. Trying to create symmetry in the face will only lead to more problems. You should enjoy your appearance and don’t focus on symmetry. I hope this helps and good luck from New York City Plastic Surgery.
