Why is the price difference for fillers so huge?? lol

The thing that surprised me the most while looking into fillers lately was the price difference. ㅠㅠ It's the same filler, but some places are super cheap while others are several times cheaper!! At first, I really didn't know what the difference was, so I did a lot of research. lol

I looked it up and found out there are so many different filler brands, and there are differences between domestic and imported products :) I was also fascinated to learn that the price varies quite a bit depending on where it's injected and how many cc is used!! I just thought they were all the same haha.

I'm interested in jaw and nasolabial fold fillers, and when I read reviews, I see that there are so many people who are highly satisfied. ^^ In particular, many people mentioned that it feels like the facial balance is refined, making their features look sharper!! However, I'm also worried because I've heard that it can look unnatural if you get too much injected. ㅠㅠ

And I've seen so many comments saying that the doctor's design sense is also important when it comes to fillers :) I heard that even if the same amount is injected, the results differ depending on where and how it is used!! So now I understand why people say you shouldn't just look at the price lol

They say the filler procedure itself finishes faster than expected, but it seems like swelling and bruising vary quite a bit from person to person. Some people said they went straight to an appointment, while others said it was noticeable for a few days, so I think I need to schedule my appointment carefully haha.

If anyone here gets fillers frequently, I'm curious about the typical price range you pay for treatments. I'd also like to hear your honest reviews on whether really cheap promotional fillers are okay.
