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

Hi and thanks for your question.Most of the fillers we use in these days are HA fillers and they will go away in 9-10 month. I do not see any abnormality in your lip base on your picture but I suggest you to see an expert physician for consult and proper assessment 

Thanks for sharing your question and photo. It's hard to determine the cause based on this photo. Most of the lip filler you had previously injected should be gone at this point. I recommend an in person consultation with an experienced injector. A lip filler treatment could certainly help improve symmetry of the lips.
