Lip one side uneven after trauma. What can I do about it? (Photo)

first things first: you have to let your body heal prior to getting any filler to improve assimtries, I would reccomend you to wait at least a month to consider if lip filler is an option, the tissue around the mouth area tend to swell and inflamate a LOT, and also it take more time than other areas

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

I'm sorry to hear what happened to you. Before considering fillers to address the asymmetry you will want to let the area fully heal, including the cut. Once this has occurred if you still have concerns you can visit with an expert injector for treatment.
