I'm worried about the cost of cosmetic procedures abroad. Do any of you have experience with this?

Hi everyone, I'm Quynh from Vietnam. I've wanted to try some cosmetic procedures in Korea for a long time, but I'm really worried about the total cost of the trip. Not only the cost of the procedures themselves, but also airfare, accommodation, food... I don't know how to plan properly. Can anyone share their experience? How long should I prepare beforehand?

I'm also not sure how many days I should stay there. I've heard that some procedures require recovery time, but I'm not sure how long. Should I ask for a few weeks off from work, or just a few days? I'm afraid that if I don't prepare thoroughly, I'll waste money.

Can you advise me on how to adjust my budget? How much should I start saving, and should I book in advance or check directly when I get there? I want to make a smart decision, not rush into it. Thank you so much!
