Confused about calculating the budget for aesthetic procedures in Korea, can anyone help?

Hello everyone! My name is Bunga, I'm from Indonesia and I'm seriously considering getting an aesthetic procedure in Korea. But honestly, I'm a bit nervous about the budget since this is my first time traveling alone for something like this.

My question is, how long do people usually need to stay in Korea for aesthetic procedures? I've heard some say just a week, but others say two weeks are needed for recovery and follow-up check-ups. Is that true? Because if I have to stay longer, the costs for hotels and transportation will add up significantly...

Also, regarding the overall budget, what should I prepare besides the procedure cost itself? I've tried googling, but the prices vary so much across different sources, making me confused about what's realistic. Has anyone here experienced this before? How did you plan everything without stress?

Thanks to anyone who can share their experiences or tips! I'd love to hear from a real user's perspective, not just from internet ads.
