How do foreigners find clinics in Korea?

Hi everyone, I'm Thanh from Vietnam. I'm planning to go to South Korea for some beauty/aesthetic procedures, but I'm a bit worried about finding a trustworthy clinic. I don't speak Korean, so I don't know who or where to ask to find a reputable place.

Has anyone here had a similar experience with consultations or procedures? I'd like to know what you usually check before deciding on a clinic. Do I need to ask about interpreter services, or do many places already have English/Vietnamese support available? I'd also like to know how communication works when meeting the doctor and if there's anything I need to prepare.

I just want to gather more information from you all before making a decision. Thanks to anyone with experience who can share!
