Yes, this type of upper lip asymmetry can be seen, and it may come from natural anatomy, uneven volume in the central lip tubercles, scar tissue, prior filler, muscle movement, or differences in how the lip rolls inward and outward. The best treatment depends on whether one side is too full, one side is deficient, or the central lip shape is being pulled unevenly. If there is excess tissue on one side, a small surgical lip reduction or mucosal adjustment may help. If one side is lacking volume, very conservative filler or fat grafting may improve balance. It is important to be cautious with surgery on the upper lip, especially near the tubercles, because small changes can be very visible. Over-reduction can flatten the lip, affect the smile, or create new asymmetry. If the issue is mainly dynamic, meaning it changes when you smile, speak, or pucker, Botox in selected muscles may sometimes help, but it must be used very carefully to avoid speech or smile changes. My advice would be to see a facial plastic surgeon or oculoplastic/plastic surgeon experienced with lip surgery. Bring relaxed, smiling, and puckering photos. The goal should be subtle improvement in symmetry, not complete perfection, because lips naturally have some asymmetry and overcorrection can look less natural.
