Thinking of going to Seoul to get double eyelid surgery. Is it worth it?

Hi, my name is Net and I'm from Thailand. I'm currently interested in going to Korea for revision eyelid surgery because I've seen many positive reviews from friends and online. However, I'm hesitant about whether it's really worth the long journey and the costs of flights, accommodation, and everything else.

Has anyone had this procedure done before? Do they really say it improves the appearance of the eyes? What are the procedures like? I'm worried about post-operative care. Would it be difficult to do this from abroad? Also, how long does the round trip take, and how much time off from work would I need?

One more thing: I'm not sure if I should try a simpler procedure first before going for permanent eyelid surgery in Korea. Is there a risk of not being satisfied with the results afterward? I'd appreciate advice from locals or anyone who has gone through this decision-making process. Any insights would be greatly appreciated.
