How do foreigners find clinics in Korea?

Hi everyone, I'm Dung, and I'm planning my first trip to Korea for some aesthetic procedures. I'm a bit worried about finding a trustworthy place since I don't speak Korean, only English and Vietnamese.

For those of you who have experience or have been before, I'd like to ask what I should check when looking for a clinic. For example, do they offer English support or even interpreters? Or how can I tell if a place is reputable?

I'd also like to know what questions to ask during the initial consultation to feel more at ease. Can anyone share their experiences? Thank you all so much!
