Worried about the budget for beauty treatments in Korea for the first time

Lately, I've been thinking about going to Korea for a cosmetic procedure, but I'm really scared. It's not the techniques or the doctors I'm afraid of, but rather the fear of not calculating all the costs. I've never traveled abroad for something like this before, so I don't know how long I need to plan to stay, how much plane tickets will cost, or how much hotels will cost. Besides the surgery fee, there are consultation fees, medication, aftercare... I'm afraid I'll run out of money halfway through 😅

I'm wondering if I should save up money slowly and then go, or wait for a plane ticket sale. Has anyone gone through detailed planning like this before? Does the hospitalization or recovery time affect the number of days I need to stay? I've read that some people stay for 2 weeks, others for a month, but I'm not sure if it depends on the type of procedure.

Furthermore, I only want to work with an experienced and reputable doctor, but I also don't know when I should contact them for inquiries and preliminary preparations. Can anyone who has planned a trip like this share their experience with me? I feel like there are still so many things to consider 💭
