Are there many cases where people regret getting fillers?

The scariest thing about considering fillers is regret. I start this because I want to look prettier, but I think it would be really stressful if I ended up looking unnatural or having too much after getting them. I'm especially worried because my face is something I see every day, so even small changes would feel significant.

I've heard that while many people around me are satisfied with fillers, there are also surprisingly many who regret getting them and end up having them dissolved. I've especially seen stories about how getting too much injected makes the face look unnatural, haha. So I'm becoming more cautious. I did it to look prettier, so I would be really upset if it ended up looking awkward instead.

I only want a natural change, but I am worried that I might be recommended to get more injected when I go for a consultation. I’ve heard that moderation is key with fillers; is that actually true? I am also wondering if it is better to start with just a small amount and see how it goes. I have also seen a lot of advice that you should be more conservative, especially with your first filler treatment.

I'm also scared because I've heard that fillers spread or your face looks unnatural over time. I'm curious if that really happens often, and I'd like to know which areas are less likely to result in regret.

For those of you who have actually regretted getting fillers, please share your honest stories!! Conversely, it would be helpful if you could also tell me about the areas where you were really satisfied with the filler injections~~
