About 5 years ago, I had non-incisional double eyelid surgery at a place in Apgujeong
After about 3 years, it all came undone, so I looked into the cost of revision surgery
The place where I had it done said it would be 2 to 3 million won
Since I had it done there, I thought it would be cheaper than other places
Other places are around 1 to 2 million won even for revision surgery
I think you really need to research carefully before going the first time
