I'm hesitating about the budget for beauty consultations in Korea. Can anyone offer some advice?

Hello, my name is Earn and I have a question for experienced ladies out there. I'm interested in consulting about beauty treatments for my face in Korea, but right now my budget is really making my heart flutter. I have to consider flights, accommodation, food, and so many other things. I don't know how many days I should book for the trip and I need to figure out a budget beforehand.

I've browsed online, but the prices vary so much. I don't know which information to trust. I think if I go, I'll need to stay for 5-7 days to have enough time for consultations, choosing products, and waiting for initial results. But honestly, I'm not sure how much all of that will cost, even roughly, or if there are ways to save money.

If anyone has been before, please share your experience. How many days did you stay? How did you plan your trip? How did you make payments? And I'd like to know how suitable it is. Thank you so much! I'm looking forward to hearing from many of you.
