Uneven lips after lip lift. Permanent recommendations to fix these?

I have addressed this very issue in one of the textbook chapter I authored for plastic surgeons on lip reshaping surgery. Most postoperative asymmetries are actual pre-operative asymmetries that were unrecognized before the surgery. The upper lip lift may have inadvertently exaggerated a mild asymmetry of such as that can be seen in your Cupid’s bow.

Therefore, it is important that an experienced lip lift surgeon invest the time to preoperatively highlight asymmetries of your upper vermillion border as well as its lower. It’s also important that the surgical markings are done with magnification and calipers to address these asymmetries.

If you have not done so already, consult with your original surgeon or seek one who is very experienced with the important nuances of lip reshaping surgery including lower lip V-Y plasties from which you may benefit in term of improved interlabial harmony.
