This is my first time going abroad for cosmetic procedures; can anyone help me with planning?

Hi everyone, I'm Suong from Vietnam. I'm thinking about going to South Korea for a cosmetic procedure that I haven't considered in a long time. But right now, my main concern is the finances and planning the trip. I'm unsure about the cost, considering airfare, hotel, food, and the procedure itself – it's really stressful.

I'd like to ask if anyone has any experience with this? How long should I stay in Korea to ensure a smooth recovery without wasting money? I heard that a few days of follow-up monitoring are needed, but I don't know the exact length. And are you going alone or with someone? I'm quite worried about communicating and taking care of myself there.

If you have any advice on how to save money or how to plan a trip effectively, please help me. I'm trying to save money but still want to make sure I choose a safe and reputable place. Thank you so much!
