Hey guys, what if I'm doing a consultation in Seoul but don't know Korean?

Hi everyone, I'm Chi from Vietnam. I'm planning to fly to Seoul to learn about cosmetic services, but I'm worried about the language barrier. I only know English and Vietnamese; I can't speak Korean. I'd like to ask if anyone has any experience with clinics, and if knowing Korean is sufficient for consultations, or if English is enough?

I've heard that Seoul has quite a few clinics catering to international clients, but I'm still not entirely sure. Has anyone in this group had a consultation without speaking Korean? What should I prepare to avoid major misunderstandings? I've considered going with someone who speaks Korean, but I'm still not sure if it's necessary.

Thank you for sharing your experiences!
