Want a treatment in Korea but confused about budget & planning... has anyone been there?

Hi everyone! So I'm seriously considering going to Korea and trying aesthetic treatments there. But honestly, I'm still really nervous about the budget and logistics. I've never traveled alone for medical reasons like this before, so I'm a bit overwhelmed.

What I want to ask is, for certain types of procedures, how many days do you usually spend there? Can you go home right away or do you have to stay a few days for follow-ups? Because if you calculate it from here, flight + hotel + the procedure itself... I'm still unclear about the total cost. I tried googling, but the prices are all over the place, making me even more confused.

Has anyone ever been to Korea for treatment? How did you plan? Was it worth it compared to Indonesia? I'd also like some tips on finding a safe and trustworthy place without falling victim to over-promising clinics. Any help from you all would be invaluable! Thanks in advance ❤️
