How do foreigners find reputable clinics in Korea?

I'm Hien, from Vietnam, and I'm planning to go to South Korea for some minor aesthetic adjustments. However, I'm quite worried about finding a trustworthy clinic because I don't know where to start and I don't speak Korean.

Are there any foreigners here with experience? Has anyone done this before? I'd like to know what you usually check when choosing a clinic. And most importantly, can anyone help me understand if I need to request an interpreter or if there are clinics with English-speaking staff?

I'm also unsure about what questions to ask during the initial consultation. I'd appreciate it if you could share your experiences and advice. Thanks a lot! 💕
