My left jawline seems lower than my right jawline. What can correct this? (Photo)

Everyone is asymmetrical to some degree and you are within normal limits. If it is particularly bothersome you can use a combination of fillers and Botox to improve your concerns. See an experienced injector for an evaluation.

Facial asymmetry exists in every single individual on this planet. There’s absolutely nothing that you should be doing about that in your face. I hope this helps and good luck from New York City plastic surgery.
