Worried about the budget for Korean skincare + trip planning 😅

Hello, my name is Bam. I've been wanting to go to Korea to do something I've been interested in for a long time, but right now I'm also feeling down about the budget 😭. I don't know if I should set aside one amount or multiple amounts for this trip. Could anyone who has been before please tell me what you considered? For example, regarding travel expenses, I'm arguing with myself about whether I should find a luxurious place to stay for half a month or save money. And how many days should I rest before I can comfortably travel back?

I'm wondering how anyone else saved up their budget, or if there are any methods that can help with the overall planning, such as flight costs and accommodation. I'm considering how many days I might need to rest after the procedure before I can go home. If I'm going to spend money, I want it to be worthwhile and safe for my health.

Could anyone who has felt the same anxiety or has already prepared for such a trip share their experiences and advice? I'm still unsure whether to go this week or wait until I've saved enough money. Thank you in advance! 🙏
