When consulting about beauty procedures in Seoul, is English or Chinese sufficient?

Hi everyone, I'm Mei. I'm currently considering some skincare treatments in Seoul. My English is pretty good, but I'm worried about misunderstandings when consulting at a cosmetic clinic, especially regarding technical terms or details. I'd like to ask experienced women how you handled the language barrier?

I've heard many clinics in Seoul offer translation services, but I'm unsure if it's free or requires an extra fee. Has anyone used a professional translator? Or is English communication sufficient? I really want to ensure I can accurately express my needs and concerns during the consultation and avoid any misunderstandings later due to language barriers.

If any of you have recently had similar consultations in Seoul, could you share your experiences? I'd especially like to know about communication flow and the most effective way to schedule appointments and communicate. Thank you!
