I've noticed over the years that I've developed an eyebag on one side that appears when smiling. I have some eyebags showing when not smiling as well, but they're equal on both sides and not that bothersome. The problem is that when I smile the left side eyebag looks huge. I've had tear trough fillers on both sides and also tried 1 unit of botox that was put right on the under eye, but neither of them helped. Could blepharoplasty solve this problem?
