Are there any people who say they developed sunken cheeks after receiving Bollneumer?

A while ago, I was concerned about my nasolabial folds and deep cheek fat, so I tried Bollneumer for the first time.

I don't naturally have a lot of fat on my face, and when I was looking into lifting procedures, my biggest concern was actually sunken cheeks.
I do want to tighten up the sagging areas, but I was worried that if I lost weight in the center of my face or on the front of my cheeks, I might end up looking haggard.

For now, perhaps because it hasn't been long since the procedure, I don't feel like my cheeks look particularly sunken. On the contrary, I am satisfied because my nasolabial folds and deep cheek fat seem slightly more refined.

However, while looking through reviews, I occasionally saw people mention that it looked fine at first but the cheeks seemed to lose their volume over time, so it is a bit concerning.

I am especially curious about how it is for those like me who don't naturally have much cheek fat.
I would like to hear from those who have received the Bollneumer multiple times about whether anyone has noticed their cheeks sinking over time, or if it is something I don't need to worry about too much.
