Nervous about budgeting for aesthetic procedures in Korea... how do you plan?

Hi everyone, I'm Wulan from Indonesia. So I've been thinking about trying a certain aesthetic procedure in Korea for a while, but honestly, I'm a bit anxious about the budget and planning. This is my first time traveling alone for something like this, so I'm completely clueless about the timeline and costs.

What I want to know is—how long do we usually need to stay there? Do we have to come in advance for the first consultation, or can we just go the same day? And what about recovery time? I haven't dared to ask directly at the place because I'm afraid I've already committed. Flights, hotels, food—all of that requires a budget, besides the procedure itself.

Has anyone planned a trip like this before? How did you allocate your budget and organize everything? I'd really appreciate it if anyone could share their experiences or practical tips. I want to really plan things carefully, not just go and regret it, haha. Thank you!
