Confused about how to budget for aesthetic treatments in Korea, any tips?

Hi everyone, I'm Utami from Indonesia. So I really want to try aesthetic treatments in Korea, but honestly I'm a bit nervous about arranging everything on my own. This is my first time planning a trip for something like this, so there's a lot I don't know.

How do I prepare the right budget? I need to calculate flights, hotel, the treatment itself, and food. But honestly I have no idea what the treatment prices are there... how much do people usually allocate for something like this? How many days is enough for treatment, recovery, and a little bit of enjoying myself? I'm worried I'll book something too short or waste money on a long stay that I don't even need.

Has anyone arranged a trip like this before? What tips do you have for me? Would it be better for me to contact the clinic or do an online consultation first before booking my flight? I also want to know how long the downtime usually is for common treatments? So I can plan when I need to go back to work.

Sorry if I have too many questions, I'm just really overwhelmed but excited too. Thanks in advance if anyone wants to help! 😅
