Has anyone gone for a consultation in Seoul and only spoken English or Vietnamese?

Hi everyone! My name is Hoa, and I'm planning to fly to Seoul to learn about beauty services there. But I'm a little worried about the language barrier 😅 My English is only so-so, and I know almost no Korean at all.

Have any of you ever had a consultation in Seoul? Did the doctors or consultants speak English? Or did I need to find an interpreter or some other service to help? I'm feeling a bit overwhelmed and don't know how to prepare 😭

Does anyone have any experience or advice on this? Thank you so much!
