How to fix asymmetric lip gap? (Photo)

Hello, and thank you for your question!
I believe that you would be a great candidate for a procedure that I call Aesthetic Facial Balancing. A large part of my practice is using this procedure.  What this means is evaluating a patients face and bringing the features into harmony by making adjustments with either hyaluronic acid or fat.  The most important component of a fillers treatment is the practitioner administering it. I take filler and balance all features in your face from top to bottom to make them work together to 'unlock' your beauty. This procedure is not just a filler intervention augmenting the cheeks and lips, but as in overall, non surgical way to shape the face in a different way to create natural appearing results. 
I hope this helps!Dr. Rian Maercks, M.D. 

Thank you for your question. You would get a nice improvement with lip fillers. These fillers, (Volbella, Restylane, Juvederm) are good to create a symmetrical lip. Nova threads can be used to improve lift and shape. Implants or fat are alternatives. Technique will be important here, so you'll want to see someone meticulous. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

Dear annabananaaa1,
I typically use Juvederm for my lip sculpting. There are two main focuses of lip injections, adding volume and actually sculpting the shape. Both involve injecting the filler in different areas of the lips and patterns.
I would recommend finding a plastic surgeon to perform you lip injections. Most of my patients have results that last at least 6 months.
