Why is the price difference for Botox so big?? Haha

The most surprising thing I found while looking for a dermatologist lately was the price difference for Botox!! It's the same product, but some places are super cheap while others are several times more expensive ㅠㅠ So I became really curious about what makes them different lol

At first, I thought all Botox was pretty much the same, but after looking into it, I found out there are differences between domestic and imported products, as well as variations depending on the dosage and the area treated :) I was especially fascinated to hear that jaw Botox and forehead Botox feel completely different!! My friend said she was extremely satisfied after getting jaw Botox, but since I haven't tried it yet, I'm still thinking about it ^^

But I feel a bit uneasy about really cheap Botox. When I look at promotional prices, there are a lot of places that are really cheap, but I'm not sure if there are extra costs for those or if there is a difference in the dosage. It's even more confusing because when I read reviews, some people say the effects wore off quickly, while others say they lasted longer than expected.

I also saw a post saying that the doctor's skill is important when getting Botox!! I heard that even with the same Botox, the results can vary depending on where and how it is injected :) So I thought it might be a bit risky to just go based on the price!!

I especially want a natural look, so I don't like it to be too obvious haha. I get a little scared when I see reviews saying it looks awkward when smiling or makes facial expressions unnatural ㅠㅠ But I keep being interested because I hear that if it fits well, it makes your whole facial impression look more refined!!

For those of you who get Botox frequently, I'm curious about the typical price range. ^^ Also, I would appreciate it if you could let me know if you can really feel a significant difference between domestic and imported Botox.
