How do foreigners find a trustworthy clinic in Korea?

Hello, my name is Som. I'm planning a trip to Korea for beauty treatments and I'm worried about finding the right clinic. Has anyone been before? I'm wondering what you all check to make sure a clinic is trustworthy.

My biggest concern is language and communication. If a foreigner goes alone, does the clinic have interpreters or speak English? I want the doctor to explain the details of the procedure clearly so I don't misunderstand.

What should I ask during the initial consultation? Can anyone recommend methods or things to check? I'd love to get tips from your real experiences. Thank you so much!
