Is there a definite difference between domestic and imported fillers?

It's still hot.
I am writing this post because a question suddenly came to mind while looking through reviews of plastic surgery or cosmetic procedures. When I looked into getting fillers, I noticed they are divided into domestic and imported products. Since there is quite a price difference, I am debating which one to choose. Many people around me say that since I am putting something in my body anyway, it is safer and lasts longer to pay a little more for imported products, while others say that domestic technology has improved so much these days that there isn't much difference, so I am confused. For those of you who have actually received filler treatments, do you feel a definite difference between domestic and imported products? I would appreciate your honest advice on whether the difference in terms of duration, shape retention, or foreign body sensation is worth the price!
