Worried about the budget for cosmetic consultations in Korea

Hello everyone, my name is Tum. Has anyone here consulted with beauty clinics in Korea before? I'm currently thinking about trying it out once, but I'm actually worried about the cost because I have to calculate so many things at once: flight tickets, accommodation, the number of days I need to stay there. Right now, I'm still confused about how much I need to prepare to be sufficient.

I'm wondering, how many days do people usually stay in Korea for a consultation, waiting for results, and check-ups before returning home? Can anyone offer some guidance on how to plan? I'm not sure yet which city is the most economical or which days are the cheapest.

I'd also like to know if anyone has experience with budget planning like this. Are there any techniques that can help save money? Or should I go back again and again? I'm seeking opinions from everyone in the community.
