Are there cases where people regret getting Botox? ㅠㅠ

While looking into Botox, I suddenly got curious about something. When I read reviews, there are so many stories about satisfaction, but I occasionally see posts saying it was disappointing.

So I became curious about the usual situations where people regret getting Botox. I wonder if it's because the effect was weaker than expected, or if it's because I had too high expectations.

I naturally have a bit of jaw muscle, so I'm thinking about getting jaw Botox, but since it's my first time, I'm worried about a lot of things haha. People around me say it's no big deal, but I find myself looking up every single review for no reason.

I heard that Botox is a relatively simple procedure, but since it is being done to my own face, I can't help but be cautious. Especially when looking at online reviews, I see that while some people are highly satisfied, others were disappointed because they had expected a bigger change than anticipated.

Also, since everyone has different face shapes and muscle sizes, I think the results might feel different even with the same Botox. That is why I am even more curious about your actual experiences :)

I think I would be satisfied if my facial contours were just slightly refined and looked softer rather than undergoing a dramatic change, but I am curious to know if everyone else's results were similar to what they expected haha.

If anyone has had Botox, please tell me honestly about the things you were satisfied with, but also any downsides!! I'm really curious as someone getting it for the first time ^^
