Are there any consultants in Seoul who only speak English or Vietnamese?

My name is Loan, and I'm planning to go to Seoul for a beauty consultation in the next few months. However, I'm worried about communication, as my English is only average, and I don't know any Korean. Have any of you experienced this situation? Do clinics there have staff who speak English or Vietnamese to help?

I plan to consult about several treatments, and of course, I want to understand everything clearly without getting lost or needing translation. Does anyone have any advice on what I should prepare, or should I bring a translator? I've never been to Korea before, so I'm a little anxious. What experiences do you have?
