Navigating your beauty budget for the first time in Korea

Hello everyone, I'm Trinh from Vietnam. I'm considering a trip to South Korea for some cosmetic procedures, but I'm feeling a bit overwhelmed with planning the finances for the entire trip. Since it's my first time, I'm unsure how much money to prepare, when to fly, and how long to stay for it to be reasonable.

I'm mainly concerned about the costs for flights, accommodation, and recovery time. I've heard from some people that staying for about 1-2 weeks is necessary to allow enough time for consultations, procedures, and follow-up checks, but I'm not sure if I should stay longer. Can someone help me understand the general process better? I also have no idea about the pricing, so what would be a suitable budget for the entire trip?

Thank you in advance to anyone who has gone through something similar and can share their experience. I really want to do this, but I also want to make sure I can manage my finances well.
