What are the criteria for a clinic that produces natural-looking Botox?

I've been stressed about my jawline lately, so I'm seriously considering getting Botox haha. A lot of people around me get it, so I got interested too!! But now that I've actually looked into it, there are so many clinics that I don't know where to go ㅠㅠ

I’ve heard so many times that you really need to go to a place that does Botox well to make it look natural :) I heard that even with the same Botox, the result can vary depending on the doctor's style or technique, so I’m becoming extra cautious for no reason haha. I really hate it when it looks too obvious!!

When I read reviews, some people are happy because their faces became incredibly slim after getting Botox, while others post about sunken cheeks, so it scares me a bit. I'm starting to wonder if getting too much injected could actually feel like a side effect.

Also, I heard a lot of people say it's good to go to a place that properly assesses the condition of your facial muscles during the consultation. ^^ They said that instead of just using a fixed amount, the treatment needs to be designed differently for each person!! So, while price is important, I think finding a place with a thorough consultation is even more crucial.

Botox itself is less of a burden since the procedure is quick and recovery is fast, but I'm hesitating more because the results seem to subtly affect one's appearance :) Still, if it turns out well, I think I'll be less stressed when taking photos, so I'd like to try it at least once haha.

If anyone has had Botox, I'm curious what criteria you used when choosing a clinic. ^^ Please share any reviews you have about results that turned out naturally.
