Budgeting for aesthetic treatments in Korea—how do you plan it?

Hi everyone! I'm Tari from Indonesia, and I'm thinking about trying aesthetic treatments in Korea. But honestly, I get really nervous when I think about the total cost. It's not just the treatment—there's the flight, hotel, food, everything requires a budget. I've never traveled around Korea for a treatment like this before, so I'm totally lost as to where to start.

For those of you who have been or are planning to, how do you budget and plan your trip? How many days do you think are enough for one treatment plus recovery time before your return flight? And are there any options you can pay in installments? Having to pay for everything all at once can be overwhelming, hehe.

Also, do you have any tips for finding an affordable yet comfortable hotel or lodging? And what do people usually consider when planning a trip like this? I'm afraid I might miss something and end up overspending. I'd appreciate any insights from your experience! 🙏
