How satisfied are you with the fillers?

Now that I'm in my 50s, my face looks much less voluminous than before, so it bothers me every time I look in the mirror. My nasolabial folds look particularly deep, and my face looks tired overall, so I'm considering fillers based on recommendations from others. However, I can't easily make a decision because I'm worried it might look unnatural. I'm concerned that fillers might make my face look too puffy, and I've also heard that they can become uneven over time, so I have a lot of concerns. For those who have actually received them, how satisfied were you? I'm curious if it gives a naturally youthful look. I'd also like to know how long the effects last and if the pain is tolerable. Most of all, I'm worried about whether I'll have to keep getting them once I start. The reviews from clinics all look positive, which actually makes it harder to judge. If there are any people in a similar age group who have received the treatment, I would appreciate it if you could share your honest satisfaction, reasons for recommending it, and any downsides you experienced.
