How do foreigners find clinics in South Korea? What tests do they need?

My name is Trinh, and I'm planning to go to Korea for some cosmetic procedures, but I'm really worried about finding a reputable and safe clinic. I don't speak Korean, so does anyone have experience and can share how to find a trustworthy clinic?

I'm especially interested in knowing what questions to ask during the consultation. For example, do they offer interpreter services, or what is the consultation fee? I've heard that some clinics have staff who speak English or other languages, but I'm not sure how to verify that they are financially sound and safe.

Have you encountered any difficulties, or do you have any advice for first-time foreign visitors? Thank you everyone! 🙏
