How can a foreigner find a reliable clinic in South Korea?

Hi everyone, I'm Ping. I'm currently considering getting a cosmetic procedure done in South Korea, but as someone from China, I'm a bit unsure where to begin. I've read many recommendation posts in Chinese, but I feel some information might be incomplete.

What I really want to ask is, how did you foreign friends who have had cosmetic procedures in South Korea find clinics? What are some ways to determine if a clinic is truly reliable? My biggest concern right now is communication—do they offer Chinese translation services? Can we communicate effectively in Chinese or English during consultations? Or do I need to bring my own translator? Has anyone experienced this?

Also, what do you usually check before going to a clinic? For example, the doctor's qualifications, the clinic's business license, etc.? I'd like to hear your experiences and advice, thank you!
