Correcting lip asymmetry can be easily achieved with a small amount of Restylane or Juvederm carefully placed into the lips. Sometimes these injections have to be done in stages to gauge the results so that the area is not too plump. For the best cosmetic results please consult a board certified dermatologist with experience with these cosmetic injections.
Asymmetrical lip treatment
To correct the area of the upper lip that does not have as much volume, some well-placed lip injections should give a more even and natural appearance. Hyaluronic acid fillers such as Juvederm, Restylane, and Belotero can restore lost volume to the lips without looking too overdone. Repeat treatments can be performed as needed to maintain the results. I would recommend visiting a dermatologist who is a dermal filler expert in order to get the most ideal results.
Some lip asymmetry is normal, but it can be adjusted a bit with filler or fat grafts. Best of luck with moving forward.
Upper Lip Vermilion Deficiency
There is a vermilion volume deficiency on the right side of your upper lip. This can be improved by either fat injections or a dermal-fat graft placed into the deficient vermilion area.
