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

Hi everyone! I'm Uyen, and I'm planning a trip to Seoul to check out some places for beauty treatments, but I'm worried about the communication barrier. My English is okay, but not great, and I don't know any Korean at all 😅 Has anyone here ever gone for consultations there using only English? Or do I need to hire a translator or prepare a script beforehand?

I'm also curious if most places there offer English support, or if I should look for places that specifically cater to international clients. I don't have high expectations, I just want to clearly understand what they advise.

Hoping you all can share your experiences to help me out! Thanks so much! 🙏
