Why does this part of my lip hang lower when I smile? (Photo)

Hello, it is hard to tell if there is an abnormality from the photos, but a year later, any filler injected should be gone now. I'd make an appointment with an experienced injector to get a consultation.

Most lip fillers last about 6-12 months, depending on the type of filler used and how quickly your body breaks it down. So there is most likely no filler left in your lips at this point. The unevenness that you see when you smile can be corrected with filler, even if there is still a little left from the previous injection. Make sure you see an experienced board certified physician to discuss your wishes. Good luck!

After a year most if not all Hyaluronic Acid fillers are gone. I like a newer HA filler named Volbella. It is soft and feels more natural after injection. See an expert Physician injector for evaluation. Best Wishes, Maurice Vick MD
