How do foreigners usually find reliable clinics in Korea?

Hi everyone, I'm Qing. I've been thinking about getting some medical aesthetic procedures done in Korea recently, but honestly, I'm a bit lost and don't know how to find a truly reliable clinic. My Korean isn't great, and I'm worried about communication issues during consultations.

I'd like to ask for your advice: how do you find clinics? Do you rely on friend recommendations, or do you search online yourself? Most importantly, how do you confirm if a clinic is genuinely professional and safe? I'm especially curious if translation services are important, or if many clinics can communicate in English now?

Also, are there any specific things to pay attention to during consultations? For example, what questions will the doctor ask, or what documents should I prepare? Can anyone share their experiences? Thanks!
