My name is Phuong, and I'm from Vietnam. I'm thinking about going to South Korea for a cosmetic procedure, but I'm really unsure about how to prepare financially and plan my trip. I'm a little worried because this is my first time considering this, so I don't know how many days I need to stay there, whether 3-5 days is enough, or if I need to stay longer for recovery.

I'm considering the cost of airfare, hotels, and other expenses I'm unsure about. Has anyone made a similar trip before? Could you help me understand better? For example, how long do you usually need to stay, do you need anyone to accompany you, or are there any "hidden" costs I shouldn't overlook? I'm also unsure about my overall budget, so I don't know how to start saving now.

I would be very grateful if anyone with experience could share their insights! I really want to understand this process before making a decision.
