Which procedure would correct folds caused by lower blepharoplasty? 3 years post op (photos)

Any treatment that would break up this scar, generally termed a "local tissue rearrangement," should help this area. The scar may no longer be straight, but it would likely be less prominent than your current scar. Although hard to tell without an in person physical exam, a regular scar revision with excision and reclosure could also help.

The information you’ve included, makes difficult to make a quality assessment.
To make an assessment regarding the outcome of any plastic surgery procedure we need to see a complete set of proper before and after pictures great
If you don’t have before and after pictures, then ask your surgeon to forward the pictures they took.
We need standard pictures.
I suggest you get in person. Second opinion consultations and avoid doing this virtually.
Considered consulting with Akio plastic surgeons in your community to see what they have to say and they are recommendations.
