For those of you who have received cheek fillers, how satisfied are you?

Hello! As I get a little older, I've noticed areas of my face starting to sag noticeably. It seems that fillers are the most popular way to add volume, so for those of you who have had them, how satisfied are you? Since fillers can cause side effects if administered incorrectly, I would like to carefully read the reviews before getting the procedure.

My cheek hollowing is particularly severe. For those of you who have received fillers for this, were you satisfied? I was originally debating between Juvereux Volume and fillers, but I heard that even if the effects appear, they take a very long time to show, and in some cases, there is no effect at all. So, I've shifted my focus to fillers. Fillers are definitely a good option in terms of effectiveness, right?
