Hesitation: Budget for beauty treatments in Korea + Travel planning

Hello, my name is Oil, and I'm thinking about going to Korea for an aesthetic procedure. However, I'm actually quite worried about the budget and planning the entire trip 😅

I'd like to ask, for someone going for the first time, how should I set a budget? I need to consider flight costs, accommodation, time off work, the budget for the procedure itself, and also medication/aftercare costs. After that, I'm not sure how many days would be ideal to stay in Korea. Some people say 5-7 days or 2 weeks, but what does that depend on?

And honestly, I'm also concerned about the preparation. For example, should I book a clinic before investing in the flight? How do I find a hospital, and is there time for a consultation? Has anyone gone alone, and how did you manage the language barrier + post-treatment care? Sorry for so many questions 😭 I'm genuinely looking for opinions from those who have done it before.
