How do foreigners find reputable clinics in South Korea?

Hi everyone, I'm Oanh from Vietnam. I'm planning to go to South Korea for some cosmetic procedures but I'm worried about finding a trustworthy clinic. Since I don't speak Korean, I'm afraid of misunderstandings about what I want. Have any of you experienced this before?

I have a few questions: What do you usually check when looking for a clinic? Do you need a place with a private interpreter, or do larger clinics usually offer English and Vietnamese support? Should I request a detailed consultation before making a decision?

Thank you so much, I hope to hear from everyone's experiences!
