Nervous about the budget for an aesthetic trip to Korea... can anyone give me some tips?

Hello everyone! I'm Zahra from Indonesia. I've wanted to try a specific aesthetic procedure for a long time, and I've finally decided to seriously go to Korea for it. But honestly, I'm a bit stressed about the overall budgeting and planning. This is my first time traveling alone for something like this, so I'm feeling a bit overwhelmed.

What I don't know yet is how to accurately estimate the total budget. There are procedure costs, then flights, accommodation, food... and I also don't know how long I'll actually need to stay there. Is a week enough or more? I'd love to hear about your experiences, especially regarding how long you took off work and your estimated total expenses. I'm still guessing and worried about running out of budget halfway through.

If anyone has done this before or is planning something similar, could you share some tips? Especially about travel timing, the ideal number of days for recovery while still being able to sightsee, and how to research suitable accommodation that isn't too expensive but is also safe. Thanks in advance!
