How do foreigners find clinics in South Korea? What should they keep in mind?

Hi everyone, I'm Trinh from Vietnam. I'm planning to go to South Korea for some beauty/aesthetic services, but I'm a little worried since it's my first time. How do foreigners usually find clinics? What websites or platforms do you usually use to search?

My biggest concern is communication – do you find clinics that offer English or Vietnamese support? Or do you go with an interpreter? I feel that understanding the procedures and what the consultant says is very important, so I'm wondering if there's any way to be more certain.

Also, what do you usually check when you first meet the clinic? Is there anything you consider a "red flag"? I want to prepare mentally and know what to ask/pay attention to. Thank you for sharing your experiences!
