I had a hollow under my eyes from weight loss which really aged me. I tried fat transfer thre times and it did not stay longer than a few weeks. It was expensive.
Then I tried a less invasive alternative which has disfigured me temporarily. It is cosmoplast and cosmoderm. It looks lumpy and bumpy and even though it breaks down in 3 mos. I want it dissolved or filled in to hide contour which is uneven.
