My right upper lips is slightly different then my left upper lips. What treatment would you recommend? (photo)

Please understand that  asymmetry in facial features is normal and there are studies that suggest a little asymmetry is actually desirable and makes your face more interesting.  However, a tiny bit of Beletero to the smaller side would make this more symmetrical.

Its difficult to say based on the photo you have shown, but it appears that your muscles that elevate your lips at an angle (levator anguli oris) may have different baseline tone.  The lighting is not symmetric in the photos, but it appears that your left melolabial fold is more prominent indicating that you raise the left side of your lip more than the right.  If this is the case, then 1-2 units of Botox to the left side would likely correct the problem.  On the other hand if the lighting is just misleading, then a small amount of filler would help even the symmetry.  See someone well respected in your area for an in person consultation to determine the right course of action.  Best of luck.

Hello,Fillers are a reasonable option sometimes (as mentioned by several physicians here).  However, I also do a procedure wherein we actually make the lips the same length surgically.  The procedure is done in the office under local anesthesia and can often improve the situation.Best of luck!
