English or Vietnamese at clinics in Seoul?

Hi everyone, I'm Hiền from Vietnam. I'm planning to explore aesthetic services in Seoul next year, but I'm quite worried about the communication issue. I can speak basic English, but I'm not very fluent, and I don't know any Korean at all.

I'd like to ask those of you who have experience there: what level of English support do clinics and beauty facilities in Seoul offer? Or has anyone been there and found staff who speak Vietnamese? I'm a bit anxious about miscommunication during consultations, since this involves my face after all.

Does anyone have suggestions on how I should prepare best? Should I learn some basic Korean or is English sufficient? Thank you! 😊
