Concerns about chin fillers

I don't have a severe receding chin, but my jaw is on the shorter side.

I was planning on surgery, but I'm too scared, so I'm considering getting chin fillers instead.

But I heard that the downside of chin fillers is that they sag over time, making it look like a witch's chin or that your jaw has dropped, so I'm wondering if I should get them removed right away in a few years.

For those of you who have gotten chin fillers, did you get domestic or imported ones, and what type did you choose?

I'm wondering if there are fewer side effects if I use imported products.
