Worried about the cost of medical tourism in Korea - anyone have experience?

Hello everyone, I'm Hanh from Vietnam and I'm currently considering a trip to South Korea for a cosmetic procedure. But I'm really overwhelmed by the total cost – not just the procedure itself, but also flights, accommodation, food, etc. I'm not sure how much to budget for and how long I need to stay for it to make sense.

I have some questions and don't know who to ask: typically, how many days do you need to stay to have comfortable recovery time before flying back? And then are there any other costs I should account for (like medication, follow-ups, etc.)? I'm worried I'll take a gamble on this and the results won't be what I hoped for.

Has anyone planned a trip like this before? How did you manage your budget? I would be very grateful to hear about your experiences – especially regarding how to estimate the actual costs and whether it's worth seeking multiple consultations beforehand.
