What can be done for uneven lips? (Photos)

I agree that consulting your orthodontist is an appropriate option.  If you have not seen an orthodontist, talk with your general dentist.  The shape of jaw and maxilla are the likely basis of this asymmetry.  If you decide not to have your bones reshaped, appropriate volume in the lip with the right filler is very helpful not a first line option for this.

Thank you for your question. Lip augmentation through fillers can create a more symmetrical lip line. I suggest that you consult with a board certified facial plastic surgeon.
Best wishes,

First, talk to your orthodontist or family physician about your dental and jaw issues. Perhaps there is a physical problem that’s causing your lips to be uneven. However, asymmetry is natural in the face. If you still want to make your lips match each other better, this can probably be achieved with a little bit of Botox to relax your overactive mouth corner and perhaps a dermal filler such as Volbella, which looks very natural, to even out your lips. Consulting with a board-certified dermatologist will help you decide what you want to do; if you are under 18 you will need your parents’ permission.
