I am looking into getting Blephraplasty on my upper and lower eye lids. I am not sure what is causing the lower bags, they came so suddenly from an eye cream (Strivectin) that I only used 2 days, my eyes swelled up really big and after a few weeks when swelling went down I was left with bags under my eyes and heavy lids. I am wondering if the bags are caused from fat that had moved or if it could be a muscle? It has been 3 months and the bags are still there along with the eye lids drooping.
