How do you find a trustworthy clinic in Korea? (foreigners perspective)

Hiii everyone! I'm Nadia from Indonesia, and I wanted to ask those who have had treatments in Korea. I'm really interested in trying some aesthetic procedures there, but honestly, I'm a bit nervous about how to find a reliable and safe clinic.

What I'd like to know is: how do foreigners usually find clinics that are genuinely good? Are there any special tips? Also, is it important to have a direct interview with the doctor before the treatment? I'm a bit worried about the language barrier too—is consulting with an interpreter common and does it yield good results?

Oh, and if something isn't clear during the consultation, is it better to ask questions directly or what should I do? Sorry for asking so many questions, I just want to make sure I'm fully prepared before I go. Does anyone have any experiences or advice? Thank you so much! 🙏
