Nervous about the budget for treatment in Korea, can anyone help me plan?

Hello everyone! My name is Lestari, I'm from Indonesia and I'm seriously considering going to Korea for aesthetic treatments. But to be honest, I'm really nervous about the overall budget. So far, I only know the price of the treatment (and it's still not fixed), but I haven't factored in flights, hotels, meals, and how long I'll need to stay there. Has anyone experienced this?

We in Indonesia aren't usually used to allocating such a large budget for a trip plus procedures, so I'm a bit overwhelmed. How many days do people usually need in Korea? Can they just fly back the next day, or do they need a few days to recover before boarding? And regarding accommodation, is it more economical to book an Airbnb or a hotel? I'm also worried about how I'll follow up from Indonesia if there are any issues afterward...

Honestly, I don't know exactly what a realistic budget is for all of this combined. Any tips from those who have been there? How do you plan and manage your costs so you don't go over budget? Please share your experiences, especially if anyone else is also traveling from Indonesia. Thank you in advance! 🙏
