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

Hi everyone, I'm Kim, and I'm planning to fly to Seoul for a consultation about some cosmetic procedures, but I'm a little worried about the language barrier. I can speak English, but not very fluently, and I know almost no Korean. I'm wondering if consultations in Seoul offer English support or if I need to speak Korean? Or should I bring a translator?

I've read online that many foreigners go, but I'm not sure if the consultation and detailed discussion about the procedures will be easy to understand in English. I'm afraid I might misunderstand information or not be able to clearly express what I want.

Does anyone have experience with this? How did you handle it? I would greatly appreciate any advice!
