Is there anyone in Seoul who only speaks English or Vietnamese? 😅

Hi everyone, I'm Ngoc from Vietnam and I'm planning a trip to Seoul to research aesthetic treatments. However, I'm a little worried about the language barrier. I can speak English, but not very fluently, and I've never learned Korean. Has anyone else visited a beauty/medical aesthetics clinic and only used English or another language?

I'm wondering if beauty/medical aesthetics clinics in Seoul require interpreters? Or are their staff generally used to foreign clients and speak English? I'm worried about misunderstanding important information or not being able to clearly explain what I need.

Secondly, does anyone have any suggestions for preparing beforehand, like learning a few Korean phrases or recommending a good translation app? Thanks everyone! 💕
