First time getting cosmetic procedures done abroad, worried about blowing my budget 😅

Has anyone here gone to Korea for cosmetic procedures? I'm considering it but honestly I'm pretty confused about how to calculate all the costs. How much time should I reasonably ask off from work? I've heard you need to budget separately for flights, hotels, food, and of course the procedure itself. I'm not sure how much it will cost since everything depends on the clinic and your individual condition.

What worries me most is the recovery time. Can I fly back the next day or do I need to stay a few days for follow-up checks? If anything goes wrong, what do I do once I'm back in Vietnam? 😟 I also want to ask whether the costs before and after include consultations with specialists and initial tests.

If anyone has experience with this, could you share? Especially tips on how to plan financially and create a realistic timeline. Thank you so much! 🙏
