Planning to get cosmetic work done abroad - budget, flights, unknowns

Hi friends! I'm thinking of going to Korea towards the end of this year for some kind of procedure. But the budget is a bit of a concern for me. Flights, accommodation, active recovery time – how much will all of this cost? If I'm going for a consultation, do I need to factor in travel time? And another question – how many preparation sessions are needed to ensure the treatment stage is smooth? When does it start to show noticeable results?

I'm very confused. Are there any people who have already done this and have a conclusive plan or good advice? For those who went to Seoul separately or to another city, how many total days do you think one needs to stay? And how should I plan the budget – are these things really expensive? I'm looking for any experiences or advice. Thank you. Help me plan well!
