How does everyone find clinics in Korea?

Hello, it's Natsuki. I'm planning to get cosmetic treatments in Korea soon, but honestly, I'm struggling with choosing a clinic. Should I look for one where Japanese is spoken, or should I try to manage with English... How do you all find trustworthy clinics?

I'm particularly concerned about the language support during consultations and whether there's a proper interpreter available. Of course, I'll check reviews on sites like these, but are there any key points or things I should look out for when actually contacting them?

Also, please tell me if there's anything I should confirm during the first visit, like preparing a list of questions beforehand. I'd love to hear from anyone who has similar concerns or experiences. Thank you in advance.
