Persistent Puffy Eyes After Blepharoplasty, TCA Peel and Tightening

I cannot begin to give advice from one photo, physical exam, and no preoperative ones as well. if you have been undergoing several "tightening" procedures without effect, I think it is wise for you too see another surgeon with a great amount of experience with eyelid surgery. An occuloplastic surgeon is an excellent option.

It is difficult to give you specific advice without more close-up photographs of your eyes. That being said, I believe you have a common problem after lower blepharoplasty. I see that you have asymmetric mid-face cheek fat descent - which is not uncommon. I believe that even though your plastic surgeon probably removed the same amount of orbital fat from both sides, the deficient SOOF and cheek fat at the right lid-cheek junction enhances the right lower lid bag. I don't think that skin tightening or TCA peel is the answer either.
I don't think that additional right lower fat pad removal, by itself, is the right answer. Sure the bag would be better, but this leaves an unnatural, flat and long lid margin to cheek distance - which will not improve with time.
The aesthetics of lower blepharoplasty require a new paradigm. Proper analysis of the lid-cheek junction is critical to the surgical plan. During a lower belpharoplasty, it is also important to assess the integrity of the orbital septum. If there is pseudoherniation or laxity of the septum, orbital-septal reset or conservative septal plication can make a big difference. Fat removal is always conservative and canthopexy, canthoplasty and volume replacement are always considered in the plan.
Now after a blepharoplasty, if your orbital septum appears intact, I would recommend volume correction of the lid-cheek junction and tear trough. Your surgeon can start with a HA filler or a more permanent micro-fat graft. Since you are not happy with your outcome after one year, I would discuss some of these options with your plastic surgeon or seek consultation with Board Certified Surgeon who is comfortable with blepharoplasty revisions.
