Want to get aesthetic treatments in Korea but confused about managing your budget and planning the trip?

Hi everyone, I'm Utami from Indonesia and I'm really eager to try aesthetic treatments in Korea. But what's making me overthink is how to manage the overall budget? Because I need to calculate everything from flight tickets, accommodation, duration of stay, down to the procedures themselves. I'm afraid I'll end up spending more than my initial plan.

So my question is, for those who've done this: how long do people usually stay if they want to get treatments? Can all procedures be done within 1-2 weeks, or does it take longer? I'd also like to know, how much of a budget buffer should be prepared for unexpected costs? And do you have any tips on the best time to go (seasonal or otherwise) to make it more affordable?

I know all of this varies depending on the chosen procedure, but I just need a general idea to start planning. If anyone has experienced this, please share your insights! Thank you so much 🙏
