Is it difficult to get counseling in Seoul when facing a language barrier?

Hi everyone, I'm Ha, and this is my first time flying to Seoul to learn about beauty treatments. My English is basic but not fluent, and my Korean is terrible 😅

I'd like to ask if it's mandatory to speak fluent Korean or English during consultations at clinics there? Or do they have interpreters or translation apps? I'm worried about misunderstanding important information about procedures and potential risks.

Has anyone else had a consultation in Seoul where their English or Korean wasn't good? How did you handle it? Should I prepare my questions in English and print them out, or should I find someone to help translate? Thank you all so much!
