I had Voluma in my cheeks about a year ago with a good result. Now, it appears to be "falling" into my cheeks to where my cheeks look like very round/full...almost like there is a tiny ball in each cheek. I have a thin face and have lost a little weight, so I'm not sure if maybe that has something to do with it or if it has actually moved. Anyone else have this issue? I'm considering getting it dissolved.
