Oh my goodness @tigertrixie you are a cancer survivor! Congratulations on beating cancer! Cut out processed sugar from your diet. I have heard that if you get cancer, to cut out the food to feed cancer cells, ie sugar in cakes, biscuits, etc. so they often say chicken soup is good, etc.That makes sense since you are a doc!
This has nothing to do with the face, but I had a double mastectomy due to cancer. Part of the recon is FG. I have had three rounds, and none of it took. This was over a three year period. I would be worried that my body absorbs the fat very quickly.
Have you had any experience with fillers in the upper and lower lids?
Fat graft to larger areas has limited take as the fat has to be injected in miniscule amounts to allow blood supply to grow. It takes a highly skilled surgeon and prp fat graft. My eyelid fat graft is at 80-90% take after 4 rounds in korea and just one more left to fingers crossed keep it at 100%. If this works, then you too could consider mvp clinic in korea as they use prp fat graft and do not try to charge 5 million like DA! MVP rates are 1.5-2 million ($1400-$1900) for full face fat graft so probably similar to fg to the breast area. I am really impressed how at 8 months the eyelid fat graft is holding up and it may be the cumulative effect of 4 rounds.
