How to Improve Symmetry of Crooked Lips?

Thank you for your question. You would get a nice improvement with lip fillers. Volbella, Restylane, and Juvederm are good to create a symmetrical lip. NovaThreads 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

If you are bothered by the asymmetry in your lips, then lip augmentation on the right side of your bottom lip with Juvederm, Volbella or Restylane would be my first recommendation. These hyaluronic-acid-based fillers look quite natural and can last anywhere from a few months to up to 18 months. The fillers are, in my opinion, the best solution as lip surgery can look unnatural. Try them out and see if they help you feel better about your appearance. Please consult a board-certified dermatologist with expertise in lip augmentation to help you with this issue.

In order to create more symmetry for the lips, a larger side or lip can be reduced by a surgical reduction or the smaller side augmented with a filler. What is important to recognize is that if your bite and jaw is crooked, that can make the lips look crooked when they really are symmetric yet tilted. Fillers can help but on inspection they will still look crooked. You need to decide with your physician which is best.

I think the plastic surgeon summed it up well. What it comes down to is which side you prefer more. If you like your right lower lip, I would reduce the left. If you prefer the left lower lip I would enlarge the right. Improvement is possible but perfect symmetry is not.

I agree with you if there is no bite problems then you do not need to have bone surgery.
The problem is that there is asymmetry with your lips, but to analyze your lis
the normal anatomy is normal but exaggerated
the upper lip is too full in the center, the white roll line is very exagerated and prominent, the philtral columns are very prominent, the philtrum is very deep.
In the lower lip there is asymmerty , ther is deep central cleft.
Work with a reputable good plastic surgeon to achieve more HARMONY.
to correct all the above might be impossible

I would recommend a top and bottom lip reduction if you are interested.
We all have biases as cosmetic surgeons. My bias is against focusing on symmetry (although I certainly see what bothers you). I think that balance between the lips, i.e., relative size between the lips where the lower lip is bigger than the upper lip, and generally shape, i.e., where there is not a tubular unshaped lip are the two big things that i strive to achieve. I perform a lip reduction (just finished one) 1 to 3 times almost every week. It is something that I focus my practice on. I cannot speak about the jaw issues but for the lips themselves a reduction seems like the best option, obviously with the goal to improve symmetry but not to chase it until the symmetry is perfect. Here is a website and video link to better understand my perspective.

The non-surgical approach would be to add a filler (Restylane or Juvederm Ultra) to the smaller side, creating the appearance of symmetry. The great thing about Hyaluronic Acid filler is that you can try this approach first with minimal costs. If after trying this filler option and you still do not like the symmetry or size, then a lip reduction would be the next step.
