Nervous about the budget for aesthetic treatments in Korea—how should I plan?

Hi everyone, I'm Vina from Indonesia and I'm seriously considering trying aesthetic treatments in Korea. But honestly, I'm a bit overwhelmed by the budget and don't know how to plan smartly. This is my first time traveling abroad for something like this, so I wanted to ask—how many days are usually ideal for a trip like this? I've heard there needs to be recovery time, especially for invasive procedures.

What makes me nervous is suddenly calculating flights, hotels, treatments, meals, and it all feels like a lot. I don't know if I should book everything in advance or if some things can be arranged upon arrival? And regarding the length of stay, is 5-7 days enough or should it be longer? Has anyone had this experience and can share tips on how to manage the finances so it's not a shock?

Also, I'm still not 100% sure which procedure I want to try, so I think I'll need a consultation first. But consultations might have costs too, right? Anybody been through this? This deliberation phase is a bit stressful haha. Appreciate any insights!
