When looking for a clinic in Korea, how do people find reliable ones?

Hello, it's Kana. I've been seriously considering cosmetic procedures in Korea lately and wanted to ask for advice on choosing a clinic.

I'm worried about whether Japanese will be available, but I'm also anxious about having medical explanations entirely in Korean. How do you all find reliable clinics? Do you decide based solely on social media reviews, or do you go through an agency?

What I'm particularly concerned about is whether there will be a proper interpreter during consultations, or if the staff will speak English or Japanese. I'm worried my requests won't be communicated properly if there's a language barrier... If anyone has gone through this, I'd love to hear what you checked for!
