Is there a difference between imported and domestic lip fillers?

Hello. I had lip fillers done a while ago, and now it's time to get them again. I'm not sure whether to choose domestic or imported fillers this time.

What I want is not a dramatic increase in lip size, but rather a slight boost in overall volume and a naturally refined lip line. I don't want it to look unnatural from being overfilled, so a natural result is my top priority. However, I am confused because there are rumors that while domestic products are more affordable, imported fillers offer better longevity and shape, whereas conversely, there are also many claims these days that domestic products are quite good.

I am also curious if there is actually a significant difference between domestic and imported products in terms of lifespan, naturalness, and texture.

I am even more conflicted because the price difference seems greater than I expected. If anyone has actually received lip treatments using domestic or imported fillers, I would like to know which product you chose. I would also appreciate it if you could share your actual satisfaction levels regarding duration, texture, and naturalness.
