What would help minimize the appearance of lingering swelling 6 months after blepharoplasty? (photo)

At six months, your results are final and you are no longer swollen.
What you’re looking at is the long-term outcome of the procedure.
I don’t think a treatment for swelling is going to change your outcome.
If you have concerns regarding your outcome, then follow up with your provider.
To make a quality assessment regarding the outcome of any plastic surgery procedure we usually need to see a complete set of proper before and after pictures.
If you don’t have before, and after pictures, then ask your surgeon to forward the pictures they took.
I’m usually not a fan of removing skin from the lower eyelid.
Doing so will create a premature ectropion at some point.
Whenever skin is removed, there may be a sense that the skin that was not removed. Looks a little more redundant.It’s really not possible to assess your outcome without seeing before pictures.
Follow up with your provider or schedule a few in person second opinion consultations with other providers in your community if you are motivated enough to consider having revision surgery.
I don’t think there is a non-surgical approach to your concern.
