First time going to Korea for medical aesthetics, how should I plan my itinerary and budget?

Hi everyone, I'm Xiao Yi. I've been thinking about getting a treatment in Korea recently, but honestly, I'm a bit anxious. It's not just the cost of the procedure itself, but also flights, accommodation, and food. I'm not sure how much money I need to prepare. I've heard that recovery periods vary greatly depending on the procedure. Some might require about a week before I feel comfortable going out, while others seem to only take a few days? What's most confusing me right now is how many days off work I should request.

Are there any sisters out there who can share how you planned your entire trip? For example, do you need to factor in time for pre-operative consultations and post-operative check-ups? I'm wondering if I should start saving money a few months in advance, but I'm also unsure about the specific budget range... It feels like the information online is all over the place, and sometimes it just makes me more confused.

Also, I wanted to ask everyone, would it be more troublesome to go alone? Or is it better to find a friend to go with for peace of mind? I'm a little nervous and would love to hear your advice and experiences. Thank you!
