How do foreigners find clinics in South Korea?

I've been planning to go to Korea for some minor cosmetic procedures, but I'm really unsure where to find a reputable clinic and how to ensure it's trustworthy. Since I'm Vietnamese, language will be a challenge. Has anyone in the group been there before and can share their experience?

I'm worried about how to check a clinic's history, whether they offer English or translation services, or how to identify experienced doctors. I also want to know what to look out for during a consultation and what questions to ask to feel more confident. Has anyone had the good luck of finding a good clinic?

Thank you everyone for your help! Your practical advice would be a great help.
