How can I find a trustworthy clinic in Korea?

Hello, this is Nao. I'm thinking about getting a procedure in Korea next month, but honestly, I have no idea how to find a trustworthy clinic... I'm especially worried about the language barrier.

For all you foreigners out there, what points do you check when choosing a clinic? Being able to have consultations in Japanese or English is really important, right? I'm also curious about whether they have interpreters available. If there's anything I should confirm before actually going for a consultation, I'd love to know.

I've been looking at social media and review sites, but there's just too much information and it's hard to decide... How does everyone make their final decision? If you have any good methods, please share them with me. Thank you in advance!
