Bottom line: just skip it.
Perhaps because I went shortly after it opened, the director consulted very actively and cheerfully.
They seemed confident with semi-out and natural-glamorous crease styles. They anticipated all the questions I would likely ask and told me first about the crease line, surgical method, and photos. They spoke very smoothly.
But it was more expensive than expected. It is 2.2 million won just to re-suture a loosened crease... With same-day and review discounts, it comes to the high 1-million-won range, but that is not much different from much more famous, long-established hospitals in Apgujeong and Sinsa. Also, after researching a lot, I was convinced my eyes did not need ptosis correction, but they recommended ptosis correction, which reduced my trust.
The interior is luxurious and pretty, and the director speaks with so much confidence that it seems like younger people could be swayed when they go there.
