I'm worried about sunken cheeks. How effective is Jubelook?

As I get older, I tend to gain weight and my facial contours become less defined, so why do my cheeks keep losing volume? No matter how strictly I diet and exercise, my belly fat doesn't seem to go away easily, but it feels like my cheeks disappear just by skipping a single meal. Because my cheeks are losing volume like this, I look older and sickly, and even trying to cover it up with makeup seems to have its limits. However, I don't want to get fillers that make my cheeks look unnaturally puffy or feel like foreign substances. That's why I was recommended Juvelook; since it stimulates the skin to help generate its own collagen, it seems to be the closest to the results I'm looking for. I plan to get the Juvelook procedure soon, but besides improving sunken cheeks, what other benefits can I expect? I want to know in detail what other effects I can enjoy beyond just volume enhancement. I look forward to advice from those who have actually received Juvelook.
