The anxiety of budgeting for aesthetic treatments in Korea, how do you plan?

Hello everyone! I'm Bunga from Indonesia. I've wanted to try a specific aesthetic treatment in Korea for a long time, but honestly, I'm a bit overwhelmed with the budgeting and planning. This is my first time traveling abroad for a treatment like this, so I'm totally lost.

What makes me nervous isn't just the procedure cost, but also flights, hotels, food, and local transportation there. Also, how do people usually handle their recovery schedule? Like, if I get a treatment, how many days should I ideally stay? Should I fly back to Indonesia immediately after the treatment is done, or do I need to stay for a few days? I'm worried that if I go back too soon, the results might not be optimal or something.

Does anyone have experience and can share their budget breakdown? I'm not asking for exact prices, but more like... how to make a realistic plan. How many days is typical? What's the approximate cost for local transport? Honestly, I don't even know exactly how much the procedure itself will cost, so there are still many question marks. Please, friends, share your tips!
