Preparing for a hearing procedure abroad - budget, flights, length of stay

Hello, friends. I'm Bolor. I'm thinking about getting aesthetic procedures done in Korea this year, and honestly, the biggest thing I'm worried about is the cost. Before I go, what exactly do I need to consider? If anyone here has experience, could you give me some advice? I'm worried about how to plan for the flight duration, the downtime, the pre- and post-procedure periods – basically all of it.
