Inquiry about language issues during consultations in Seoul

Hello everyone, I'm Kim from Vietnam. I'm planning to fly to Seoul to explore beauty services, but I'm a bit concerned about communication. I can speak basic English, but I'm not very confident, and I know almost no Korean. 😅

I'd like to ask if English is sufficient for consultations at clinics in Seoul, or if I should prepare anything else. I've heard that some places have interpreters, but I'm not sure how common that is. Has anyone who has been there before could share their experience?

Honestly, I'm not overly worried, as I'm sure clinics in Seoul are accustomed to international clients, but I want to be well-prepared before I go. Thank you all so much! 🙏
