Do cheek fat injections dissolve if I lose weight?

 The answer is, it depends.

You have different fat cell populations in your body. Certain fat cells act like fat depots. That is, they are very quick to take up circulating triglycerides from your bloodstream after you eat. They then turn them into fat but will only release that fat back as energy under starvation circumstances. This is why certain fat bulges are so hard to get rid of, but come back so quick if you gain any weight at all.

These fat depots create your shape, whether it is apple shaped or pear shaped.

Other types of fat cells, or "fast turnover cells" pick up the triglycerides at an easier pace, but will release the fat much more quickly as readily available energy.

That is why when losing weight some areas seem to "melt away", whereas the troublesome bulges seem to stick around forever.

So it is very important to choose WHICH  fat is used as graft material. Fat depot cells will stick around the longest, even as you are losing weight. Fast turnover fat cells "disappear" quickly as you lose weight.

You can read a little bit more at the link below.

What you have to understand is that it is the Fat CELLS that we are transplanting. These cells are a storage cell for fat. Therefore, whatever number of cells survive being transplanted to your face (or anywhere) should be there for life. But, if you lose weight, or with aging, you will probably lose volume in this area as these cells will likely shrink.
If the volume is gone in a year, then most likely the cells didn't survive.
