Nervous about budgeting for treatment in Korea... how do you plan it?

Hi everyone! My name is Rara, from Indonesia. I've been wanting to try aesthetic treatments in Korea for a long time, but honestly, I'm really nervous about the budget and logistics. This is my first time traveling alone for something like this, so I'm totally overwhelmed.

What I'm confused about is: how long should I stay in Korea? Can the treatment be completed in 1-2 days, or do I need multiple follow-ups? Plus, flying from Indonesia is quite expensive, so I want to know if it's worth it or if the flight and hotel will end up being expensive. Has anyone ever planned something like this? I want to save money first, but I also want to have realistic expectations, so I don't end up stressed out once I'm there.

By the way, I'm also still confused about practical things like how to research safe clinics, whether I need to arrange a translator, and when the best time to go (in terms of healing time, too). Are there any hidden costs that people often overlook? Anyone willing to share their experience or tips? Thank you in advance! 🙏
