How satisfied are you with the fillers? I want to naturally add volume.

Looking at my face, it feels like I've lost a lot of volume compared to before, so I feel like skincare alone isn't enough; that's why I'm looking into fillers. However, I don't want a drastic change in my face, and I don't want it to be noticeable to others, but just enough to slightly refine my overall impression. I've been searching through reviews, but I'm even more conflicted because people are divided on whether they were satisfied or not with the same filler. What I'm most curious about is filler satisfaction. I think satisfaction depends more on naturalness and harmony with the face than just the amount of volume gained, so I'm curious to know exactly where the differences lie. I also want to know if satisfaction varies significantly depending on the treatment area or the design. Since this is my first time getting this, I want to find a place that provides thorough consultations rather than just the cheapest option. For those who were highly satisfied with fillers, I would appreciate it if you could share your experiences or advice on what criteria you considered when choosing a clinic.
