I'm curious about the technical differences between domestic and imported filler prices!

<Domestic Attier Filler>

1CC 55,000 won , 2CC 110,000 won, 3CC 132,000 won, 4CC 176,000 won
After 3CC, 44,000 won per CC is added / The event price includes VAT.
Imported Belotero Filler
1CC 176,000 won ,2CC 352,000 won, 3CC 495,000 won, 4CC 660,000 won
After 3CC, 165,000 won per CC is added / The event price includes VAT.
The price is what you posted above~~

The price difference between imported and domestic fillers is much bigger than you might think.
I was very curious to know if these high filler prices were simply a branding thing or if there were actually noticeable technical differences.
Imported fillers are known to be superior in particle uniformity, but I would like to know how much this technological difference affects the natural look after the procedure and the duration of the filler's lifespan.
I heard that the technology of domestic fillers has also developed a lot, but I wonder if it is inevitable, or if I should choose imported fillers while accepting the high price difference.

When performing the procedure on delicate areas such as the area under the eyes with thin skin or the lips with a lot of movement,
If domestic fillers provide a similar duration and satisfaction level as imported fillers, there may not be a need to pay a higher price for the fillers.

The ultimate criterion for choosing a filler should be results, not price. I'd like to know the difference.
I want to resolve this curiosity and make a rational choice!
